DIANA POV "Good evening, Ms. Sanders." The doorman tips his cap as I breeze past him into the lobby. "Mr. Thomas wasn't expecting you." "He never is," I call back over my shoulder, grinning. "That's half the fun." I press the elevator button and check my phone. Three missed calls from Sebastian, all from this afternoon. Odd. He usually texts. But I'm not worried-I'm excited. It's been two weeks since I've seen him properly, and I've been counting down the hours. Tonight, we're supposed to have dinner. Just us. No family, no business, no Sofia hovering in the background like a storm cloud. The elevator dings. I step in, press the penthouse button, and lean against the mirrored wall. "Please be home," I murmur to my reflection. "Please be in a good mood." The doors slide open on his floor. I use my key-he gave it to me six months ago, said I was the only woman who had one-and let myself in. "Sebastian?" My voice echoes through the foyer. "It's me. I brought wine. The expensive kind you pretend not to care about but secretly love." No answer. I frown. His jacket is draped over the arm of the sofa, his phone charger dangling from the wall, his laptop open on the coffee table with a half-empty glass of whiskey beside it. That's not unusual. Sebastian leaves a trail of himself everywhere he goes. But the apartment feels different tonight. Heavier. Like the air itself is holding its breath. "Sebastian?" I try again, louder this time. "You better not be in the shower ignoring me." I walk down the hallway, my heels clicking against the marble. The door to his bedroom is closed. I can hear voices-muffled, but unmistakably two people. A low laugh. A softer giggle. My stomach tightens. "He's probably on a call," I tell myself, stopping a few feet from the door. "A business call. With Richard. Or Nathaniel. Or-" Another laugh. This one is distinctly female. I approach the door slowly, expecting an innocent explanation for why he hasn't answered my calls. I push the door open. The first thing I see is the shirt. Sebastian's white button-down, crumpled on the floor. The second thing I see is the shoes. Sofia's. The red heels she borrowed from me last month and never returned. The third thing I see is them. Sebastian is in bed. Sofia is beside him. His arm is draped across her waist, her head resting on his chest, the sheets tangled around their legs. For several seconds, I cannot move. I cannot speak. I cannot even breathe. My brain refuses to accept what my eyes are seeing. This is a mistake. This has to be a mistake. Maybe I'm dreaming. Maybe I walked into the wrong apartment. Maybe- Sebastian turns his head. His eyes meet mine. "Oh," he says. Oh. That's it. That's all he says. No scrambling. No apology. No guilt. Just oh, like I've interrupted a conversation instead of catching him in bed with my sister. "Diana?" Sofia sits up, clutching the sheet to her chest. Her voice is soft, almost sweet. Almost innocent. "What are you doing here?" "What am I-" The words die in my throat. I look at her. I look at him. I look at the two of them together, in the bed I've slept in, in the sheets I picked out, in the apartment I helped him decorate. "What am I doing here?" "I thought you were coming tomorrow," Sebastian says. He runs a hand through his hair, completely unbothered. "You said Friday." "It is Friday." He glances at his phone on the nightstand. "Huh. So it is." Sofia shifts closer to him, her fingers trailing along his arm. She's not embarrassed. She's not ashamed. She's looking at me like I'm the one who's done something wrong. "Diana, you should have called," she says. "We would have-" "Don't." My voice comes out sharp, cutting through the room like a blade. "Don't you dare tell me I should have called." Sofia's eyes widen, but she doesn't flinch. She's always been good at pretending to be the victim. "I'm just saying-" "You're just saying?" I step into the room, my heart pounding so hard I can hear it in my ears. "You're in my boyfriend's bed, Sofia. My boyfriend. My sister." "Half-sister," she corrects quietly. Sebastian sighs. He actually sighs, like I'm the one being unreasonable. "Diana, calm down." "Calm down?" I laugh, and the sound is ugly, broken. "You're cheating on me with my sister, and you want me to calm down?" "We didn't plan this," Sofia says, reaching for Sebastian's hand. He lets her take it. He lets her lace her fingers through his like I'm not even standing here. "It just happened." "It just happened?" "These things happen," Sebastian says with a shrug. "You know how it is." I stare at him. I stare at the man I've loved for two years. The man I sacrificed for. The man I defended to my parents, to my friends, to anyone who would listen. The man I thought was building a future with me. "You know how it is," I repeat slowly. "That's what you're going with?" He doesn't answer. He just looks at me like I'm the inconvenience. Like I'm the one who's ruined his night. "I called you," I say, my voice cracking. "Three times. I brought wine. I-I was excited to see you." "That's sweet," he says, and it sounds like a dismissal. "But maybe you should go. We can talk about this later." "Later?" I feel the tears building behind my eyes, but I refuse to let them fall. I won't give them that. "You want to talk about this later?" "Diana, don't make a scene." Don't make a scene. The two people I trusted most in the world are in bed together, and he's telling me not to make a scene. Sofia is still holding his hand, still looking at me with that fake, sympathetic smile, and Sebastian is looking at me like I'm the one who's overreacting. My shock turns to heartbreak. My heartbreak turns to disbelief. And then, slowly, something else begins to burn in my chest. Something hot and sharp and unforgiving. I look at Sebastian, at his smug, careless face, and I realize-he's not sorry. He's not even close to sorry. Sofia tilts her head, her smile widening just a fraction. "You should probably go, Diana. You're upset. It's not good for you." I open my mouth to respond, to scream, to do something, but no words come. Because she's right. I am upset. I'm devastated. I'm humiliated. But I'm not broken. Not yet. And as I stand there, staring at the two of them together, I make a silent promise to myself. They will regret this. Both of them. They will regret this more than they have ever regretted anything in their lives. The realization hits me like a physical blow: the two people I trusted most have betrayed me. I don't beg. The thought solidifies in my mind like a vow. I will not fall to my knees. I will not ask him why. I will not give Sofia the satisfaction of seeing me break. I turn away from the bed and walk toward the door. "Diana." Sebastian's voice stops me. Not because it's pleading. Not because there's regret in it. It's flat. Annoyed. "Where are you going?" I don't turn around. "Home." "Come on." I hear the rustle of sheets, the creak of the mattress. "Let's talk about this." "There's nothing to talk about." My hand finds the doorknob. "You made your choice." "I didn't choose-" "Yes, you did." Now I turn. I look at him-at both of them-and I feel my heart splintering in my chest. "You chose her. Every time you called her instead of me. Every time you lied about where you were. Every time you let me believe we were building something real. You chose her." Sebastian runs a hand through his hair, frustrated. "You're being dramatic." "I'm being honest." My voice is shaking now, but I don't care. "Something you clearly know nothing about." Sofia leans against the headboard, the sheet slipping slightly. She doesn't bother to fix it. She wants me to see. She wants me to know exactly what she's taken. "Diana, sweetie, you should probably go. You're embarrassing yourself." The words hit me like a slap. Embarrassing myself. As if I'm the one who should be ashamed. As if I'm the one who did something wrong. "You know what?" I say, my voice is steadier now. "You're right. I should go. But not because I'm embarrassed. Because I refuse to waste another second of my life on either of you." I yank open the door. "Diana." Sebastian again. Still not moving. Still not getting up. "Don't do anything stupid." I pause. I don't turn around. "What's that supposed to mean?" "Just... don't." I don't answer. I step into the hallway and pull the door shut behind me. The click of the latch sounds like a gunshot in the silence. I walk through the apartment, my heels clicking against the marble floor. I grab my coat from the hook by the door. I check my bag-phone, keys, wallet. Everything I came with. Everything I need to leave. The living room is exactly as I left it. His jacket on the sofa. His laptop on the coffee table. The glass of whiskey, now watered down from the melted ice. I set the bottle of wine on the counter. The expensive kind he pretends not to care about. Let him drink it. Let him think of me every time he takes a sip. I reach for the front door and pause. My reflection stares back at me from the dark window-a woman with tear-streaked cheeks and wild eyes and a heart that's been shattered into a million pieces. This is the moment, I think. This is where you decide who you're going to be. I could go back. I could fight. I could scream and cry and demand the answers I deserve. But what would that change? He's already made his choice. She's already won. Staying would only give them another chance to hurt me. So I do the only thing I can do. I leave. The hallway is empty. The elevator is empty. The lobby is empty, save for the doorman, who looks at me with wide, pitying eyes. I don't acknowledge him. I don't acknowledge anyone. I just keep walking, my head high, my steps steady, my heart breaking with every beat. The night air hits me like a wave. Cold. Sharp. Real. I stand on the sidewalk, clutching my bag to my chest, and I let myself feel it. The betrayal. The humiliation. The grief. But underneath all of that, something else is stirring. Something darker. Something that doesn't want to cry or beg or plead. Something that wants to fight. I pull out my phone. My fingers are trembling, but I manage to open my contacts. I scroll past Sebastian's name-I'll delete it later-and I stop on someone else. Someone who could change everything. Not tonight. Not yet. But soon. I shove my phone back into my bag and start walking. I don't know where I'm going. I don't know what I'll do when I get there. All I know is that I'm done being the woman they thought I was. I'm done begging. I'm done crying. I'm done letting them win. They will never see me break again. And as I disappear into the New York night, I make a silent promise to myself-a promise that will become the foundation of everything that comes next. Neither Sebastian nor Sofia will ever see me beg for their love again. And when I'm done with them, they'll wish they never crossed me.

DIANA POV The cab pulls up to my parents' townhouse at half past ten. The lights are still on in the front windows-Victoria Sanders never sleeps before midnight, and Alexander never sleeps before the markets close in Tokyo. I pay the driver, step out onto the sidewalk, and stand there for a moment, looking up at the only home I've ever known. I don't know why I came here. I should have gone to Olivia's. She would have opened the door in her pajamas, taken one look at my face, and poured me a glass of something strong without asking a single question. But some part of me-the part that's still eight years old and believes her mother can fix anything-needed to come home first. I ring the bell. My mother answers. "Diana." Her eyes sweep over me-the overnight bag, the smudged makeup, the coat I didn't bother to button. "What on earth happened to you?" "I need to talk to you and Dad." She steps aside, and I walk into the foyer. The house smells like lavender and lemon polish, exactly the same as it always does. Nothing here ever changes. Nothing here is ever allowed to. "Alexander!" my mother calls up the stairs. "Diana is here. Something's happened." He appears at the top of the staircase a minute later, still in his shirt and tie, his reading glasses perched on his nose. "It's late. What's going on?" "Can we sit down?" I ask. My voice sounds strange to my own ears. Thin. Fragile. "Please." We settle in the living room. My mother perches on the edge of the armchair, already bracing herself. My father stands by the fireplace, arms crossed. Neither of them offers me a drink or a tissue or a hug. They wait, watching me like I'm a client who's arrived with bad news about a contract. "It's Sebastian," I say. "He's been cheating on me. With Sofia." The silence that follows is not the silence I expected. It's not shock. It's not outrage. It's something careful, measured-the silence of two people deciding how to handle a problem. "With Sofia?" my mother repeats slowly. "Your sister?" "Yes." "Are you certain?" "I walked in on them." My voice cracks. "They were in his bed. Together." My mother exhales, pressing her fingers to her temple. "Oh, Diana." Finally. Finally, someone is going to be on my side. I lean forward, desperate for the comfort I've been craving since I walked out of that apartment. "Mom, I-" "Do you have any idea what this will do to our family?" I blink. "What?" "Sebastian Thomas." She says his name like it's a stock that's just crashed. "The Thomases are connected to everyone, Diana. Richard Thomas sits on three boards with your father. Do you understand what kind of position this puts us in?" "I-no. I don't." I look at my father. "Dad?" He clears his throat. "Your mother has a point. This isn't just a personal matter. The Thomases are important to this family." "Important to-" I stand up, my hands shaking. "Dad, he cheated on me. With Sofia. She's our family." "She's your half-sister," my mother corrects, as if the distinction matters. As if the prefix changes the betrayal. "She's still my sister." I turn to face her. "She slept with my boyfriend. Doesn't that mean anything to you?" My mother smooths her skirt. "Sofia has always been... impulsive. You know how she is." "I know exactly how she is. That's why I'm here." "Diana, sit down." "No." I stay standing. "I want to know why you're not angry. Why neither of you is angry." My father steps forward. "We didn't say we weren't angry. But there's a way to handle these things, and screaming about it in the middle of the night isn't it." "Handle it?" I laugh, and the sound is hollow. "How exactly would you like me to handle it? Should I send Sebastian a polite note? Should I congratulate them on their relationship?" "Don't be dramatic." "I'm not being dramatic! I'm being betrayed!" My voice rises, echoing off the high ceilings. "He lied to me. For months. And you're standing there talking about boards and connections and-" "Lower your voice," my mother snaps. "The staff can hear you." "Let them hear me!" "Diana." My father's voice is sharp now, the voice he uses when he's done negotiating. "Enough. You're not a child. Start behaving like it." I stare at him. At both of them. The two people who are supposed to defend me against the world, and they're more concerned about the staff hearing me than the fact that my life has just been torn apart. "Say something," I whisper. "Please. Just once. Tell me you're on my side." My mother sighs. "It's not about sides, Diana. It's about damage control." "Damage control." "Yes. You can't confront Sebastian publicly. Do you understand me? You cannot make a scene, you cannot post anything on social media, you cannot tell anyone outside this family what happened." "You want me to keep quiet." "I want you to be smart." She stands, crossing to me, and for one hopeful second I think she's going to take my hand. She doesn't. "If this gets out, the Thomases will look like villains-which they are-but we'll look like fools. Everyone will say we couldn't keep our own house in order. Sofia will be branded a homewrecker, and you-" She pauses. "You'll be pitied. Do you want to be pitied, Diana?" "I want to be defended." "Then defend yourself by keeping your dignity." "My dignity?" I step back from her. "I caught my boyfriend in bed with my sister. What exactly do you think I have left?" "Composure," my father says. "Which you're losing." "And what about Sofia?" I turn to him. "Are you going to say anything to her? Are you going to tell her that what she did was wrong?" My parents exchange a look. It's quick, barely a flicker, but I see it. "Sofia will be dealt with," my mother says. "How?" "That's between us." "She's my sister. I have a right to know." "You have a right to a lot of things, Diana, but you don't always get them." My mother's voice has gone cold. "Now. Are you going to listen to reason, or are you going to make this worse than it already is?" The words land like stones. I stand there, in the middle of the living room, surrounded by my mother's lavender and my father's silence, and I understand-for the first time, maybe, in my entire life-that they are not going to save me. "Say it," I whisper. "Just say it. You think this is my fault." "I didn't say that." "You didn't have to." I look at my father. "You're not going to say anything at all, are you?" He picks up his glass of water from the mantel. "Your mother is right. Making a scene won't help anyone." "I'm your daughter." "And Sofia is also my daughter." I flinch. Because there it is. The truth I've spent twenty-four years pretending not to see. Sofia has always been easier to love. Sofia has always been the one they excuse, the one they protect, the one they choose. And I've always been the one they expect to be reasonable. "Say it again," I hear myself say. "Say what?" "That she's your daughter. That she gets to ruin my life and you'll still take her side." My voice is steady now. Cold. "Go on. Say it to my face." "Diana-" "No." I grab my overnight bag from the floor. "You know what? Don't. I don't need to hear it. I've been hearing it my whole life." "Where are you going?" my mother asks. "Somewhere I'm not a problem to be managed." "Diana, don't be ridiculous. It's late-" "Goodnight, Mom." I walk toward the door. "Goodnight, Dad. I'll be sure not to embarrass either of you." "Diana, wait-" I don't wait. I open the door and step out into the night for the second time tonight, and this time, the cold doesn't even register. I'm too numb. Too angry. Too done. I stand on the stoop, my hands shaking, and I understand something I've been avoiding for years: I cannot depend on my family for justice. They don't want justice. They want silence. They won't help me. They never will. So I'll have to do this on my own.

DIANA POV My apartment is dark when I let myself in. I don't bother with the lights. I drop my bag by the door, kick off my heels, and sink onto the sofa, pulling my knees to my chest. And then I let myself feel it. The full weight of it. Not the anger-not yet-but the grief underneath. The future I imagined with Sebastian. The wedding I'd started planning in my head, even though he'd never officially proposed. The apartment we were going to buy together. The life we were going to build. Gone. All of it. In the time it took to open a bedroom door. How did he discard me so easily? How did two years mean so little to him? I replay every conversation, every promise, every time he told me I was different. I search for the moment it all went wrong, and I can't find it. Because it wasn't one moment. It was all of them. Every lie he told while looking me in the eye. Every night he spent with her while I was working late, sacrificing, believing we were building something real. I press my forehead to my knees and I cry. For the first time tonight, I let the tears come. Ugly, gasping, broken sobs that shake my whole body. I cry until my throat is raw and my eyes are swollen and I can't remember what it felt like to be happy. Then my phone buzzes. I ignore it. It buzzes again. And again. I reach for it blindly, expecting Sebastian-hoping, maybe, that it's Sebastian, that he's realized what he's lost, that he's calling to apologize. It's Olivia. I answer the phone. "Diana?" Her voice is sharp with worry. "Where are you? I've been calling for an hour." "I'm home." My voice comes out wrecked. "I'm coming over." "Liv, you don't have to-" "I'm already in the car." I hear her engine turn over. "Don't move. Don't do anything stupid. Don't call him." "I wasn't going to call him." "Good. I'll be there in ten minutes." She hangs up before I can argue. The ten minutes pass in a blur. I don't move from the sofa. I don't turn on the lights. I just sit there in the dark, feeling the weight of everything that's happened pressing down on my chest like a physical thing. When the buzzer sounds, I drag myself to the door. Olivia stands in the hallway, still in her work clothes, her hair escaping its ponytail, her face set in that expression she gets when she's ready to fight someone on my behalf. "Oh, honey," she says, and the sympathy in her voice breaks me all over again. She steps inside, drops her bag, and pulls me into a hug. I cling to her like she's the only solid thing in a world that's crumbling beneath my feet. "I'm sorry," I whisper. "I didn't know who else to call." "You did the right thing." She pulls back, her hands on my shoulders, her eyes searching my face. "What happened? Tell me everything." So I do. We sit on the sofa, and I tell her about the doorman, the key, the closed bedroom door. About the shirt on the floor and the shoes and the sound of Sofia's laugh. About walking in and seeing them together, tangled in sheets I picked out. About Sebastian's careless oh and Sofia's fake sympathy and the way neither of them even tried to apologize. Then I tell her about my parents. About my mother's damage control and my father's silence and the way they made me feel like the problem instead of the victim. Olivia listens without interrupting. Her jaw gets tighter and tighter, and by the time I'm finished, her hands are balled into fists on her knees. "I'm going to kill him," she says. "Get in line." "I mean it, Diana. I'm going to march over there and-" "Don't." I put my hand on her arm. "Please. I can't handle any more drama tonight." She exhales, forcing herself to calm down. "Okay. Okay. What do you need?" "I don't know." I lean my head back against the sofa. "I don't know what I need. I don't know what I'm supposed to do now." "You're supposed to take care of yourself." "I don't even know what that looks like anymore." My voice cracks. "I built my whole life around him, Liv. My whole future. And he just... threw me away. Like I was nothing." "You are not nothing." "To him I was." "To him you were convenient." Olivia's voice is hard. "He used you. He lied to you. He cheated on you. That's not a reflection of your worth. That's a reflection of his character." I stare at her. "How do you always know what to say?" "Because I've been where you are." She takes my hand. "Remember Marcus?" "Your ex who cheated on you with his personal trainer?" "Exactly. I thought my life was over. I thought I'd never be happy again. But I got through it, and so will you." "This feels different." "It always feels different when it's happening to you." She squeezes my hand. "But here's what I know: Sebastian is a coward. Sofia is a snake. And neither of them is worth a single tear you've cried tonight." "I've cried a lot of tears." "Then they owe you a lot of reparations." I laugh despite myself. It's a weak, watery sound, but it's something. "That's my girl," Olivia says. "Now. What do you want to do?" I think about it. I think about the way Sebastian looked at me-not guilty, not sorry, just annoyed that I'd interrupted his evening. I think about Sofia's smirk and my mother's cold voice and my father's silence. I think about all the people who were supposed to love me and how easily they'd dismissed me. "I want them to regret it," I say slowly. "Regret what?" "All of it. I want them to regret ever thinking they could do this to me and get away with it." Olivia's eyes light up. "That's what I'm talking about." "I'm not going to beg him to come back. I'm not going to cry to my parents until they take my side. I'm not going to give any of them the satisfaction of seeing me broken." "Good." "I'm going to find a way to make them pay." Olivia leans forward. "What did you have in mind?" "I don't know yet." I stand up, pacing the length of the living room. The anger is back, burning hotter than before. "But I know Sebastian. I know what he cares about. I know what he's afraid of." "And what's that?" I stop. I think about all the times Sebastian talked about his family. About the pressure he felt. About the uncle who controlled everything, the one man he couldn't charm or manipulate or lie to. "Richard Thomas," I say. Olivia frowns. "His uncle? The billionaire?" "The one and only." I turn to face her. "Sebastian is terrified of him. Richard controls the family money, the family business, everything. If Richard disapproved of something Sebastian did-" "Then Sebastian would be screwed," Olivia finishes. "Exactly." I sit back down, my mind racing. The idea is half-formed, barely more than a spark, but it's the first thing that's made sense all night. "Sebastian fears Richard," I say slowly. "And Richard has the power to challenge him. To punish him. To make him regret everything." "Diana." Olivia's voice is cautious. "What are you thinking?" I look at her, and for the first time tonight, I feel something other than grief. "I'm thinking," I say, "about paying a visit to Richard Thomas." Olivia's eyes widen. "You can't just-" "I haven't figured out the details yet. But I know one thing for sure." I meet her gaze, my voice steady for the first time in hours. "Sebastian thinks he's won. He thinks he's hurt me and gotten away with it. But he's wrong. I'm going to find a way to make him regret the day he ever met me." And as I sit there in my dark apartment, with Olivia beside me and the city lights flickering outside my window, I begin to think about what Sebastian fears most-and who has the power to challenge him.
