His enemy's daughter

Serena callahan I should’ve knocked. I should’ve turned away the second I heard voices from Caleb’s study. But I didn’t. I stood there like a ghost, frozen just outside the door, listening to the sound of my world falling apart. His voice—calm, deep, familiar—melted into hers like a cruel song. Vanessa. My stepsister. Her giggle was light, breathy, coated in something I couldn’t name. It wasn’t friendship. It wasn’t harmless. It was betrayal dressed in silk and perfume. I clutched the edge of the wall, the cold biting into my skin. My heart thundered against my ribs, and a part of me prayed—desperately, foolishly—that I’d misunderstood. That there was some innocent explanation for why my fiancé and my stepsister were whispering behind closed doors. But I knew better. I’ve always known better. I just didn’t want to believe it. "She suspects nothing," Caleb said, his voice low and careless. Vanessa giggled. "She’s too perfect to think anyone would dare break her." My throat tightened. My stomach turned. I took a step back, each breath heavier than the last. Every memory of him—his promises, his kisses, the way he used to look at me—twisted into poison. And my father… my father was upstairs, weak from another round of treatment, clinging to hope that Caleb and I would carry on the family legacy. That I’d be safe. Protected. Loved. He had no idea I was standing in the shadows, choking on the truth. I wiped the tears from my face before they could fall. If love had ruined me, then I’d let power rebuild me. And if Caleb and Vanessa thought I was too perfect to fight back… they were about to meet a version of me they never imagined. That night, I didn’t sleep. I sat at the edge of my bed, numb, staring at the silver engagement ring still hugging my finger. My father had picked it out with Caleb—he said it was timeless. A ring meant to symbolize unity, loyalty, legacy. Now it felt like a joke burning my skin. By morning, my face was pale, my voice dry, but I had made up my mind—I would tell my father. He deserved to know who Caleb really was. But when I walked into his study, she was already there. Vivienne. My stepmother. Perfect posture, sharp cheekbones, and poison behind every smile. She looked up from her place beside my father’s chair, her expression unreadable. “Serena, darling. Sit.” I hesitated. Something about her tone felt wrong. Off. My father smiled weakly at me, his hand trembling slightly as he reached for mine. “Sweetheart. Vivienne said you were… troubled last night?” Troubled? Vivienne stood. “Yes, dear. She’s been under pressure lately. Understandably. Planning a wedding, managing the PR for Callahan Pharma... she’s been acting irrationally. She even accused your future son-in-law of—cheating.” I blinked. My stomach dropped. “What?” my father frowned, turning to me. “Is that true?” “No—Dad, yes, but listen—” “She barged into Caleb’s study late last night,” Vivienne continued, her voice dripping with mock sympathy, “making all sorts of wild accusations. Honestly, I think she might be… unstable.” Unstable. That word hit harder than any slap. I looked at my father, desperate for him to see the truth in my eyes. “Caleb is cheating on me, Dad. With Vanessa.” Vivienne let out a breathy laugh. “Now she’s dragging her stepsister into it. Serena, you need rest. Maybe even a short break from everything.” “She’s lying,” I snapped. “She’s trying to protect them—” “Enough!” my father said sharply, his voice echoing through the study. The tremor in his hand had worsened. He looked tired. Fragile. “Vivienne has done nothing but take care of you… and this family. Please don’t start turning on your own sister.” “She’s not my sister,” I whispered, voice shaking. Vivienne crossed the room and placed a gentle hand on my shoulder. Her grip tightened. “Sweetheart, your father can’t handle this stress. Be a good daughter… and stop making up stories.” I realized then: I was alone. Later that evening, Vanessa found me in the garden. “Serena…” she said softly, kneeling beside where I sat on the stone bench. “I heard what happened.” I didn’t look at her. If I did, I might scream. She sighed, the sound so delicate and pitiful that anyone would think she actually cared. “I know you’re hurting. But Caleb told me what you think you heard. He says it was just a misunderstanding.” I turned to her slowly. Her makeup was flawless. Her eyes glassy with carefully constructed guilt. “You’re really good at lying.” She blinked, lips parting. “Serena—” “I was outside the door, Vanessa. I heard everything.” Her expression faltered, just for a second. “I didn’t mean for it to happen…” “Wow.” I gave a hollow laugh. “You didn’t mean to steal your sister’s fiancé? Didn’t mean to giggle while planning to ruin me?” She looked down, lips trembling. “You never really loved him. You just… wanted the image. The perfect love story. But Caleb—he sees people, Serena. He sees me.” I stood up, fists clenched. “He sees a snake. Just like you.” Before she could respond, Vivienne’s voice cut through the air like a blade. “Girls.” She walked toward us in her sleek navy dress, eyes narrowing. “Is this how you plan to behave in public now? Like wild animals?” Vanessa instantly dropped her shoulders, shrinking into a picture of remorse. “She’s attacking me again, Mum.” Vivienne’s smile didn’t reach her eyes. “Serena, I suggest you compose yourself. Caleb is a powerful man. And frankly, you’re lucky he still wants to marry you after this… tantrum.” I could barely breathe. “Lucky?” I whispered. “You think I’m lucky to marry a cheat?” Vivienne stepped closer, her voice low and cold. “You signed the agreement, remember? A premature separation will trigger a scandal clause. Your father’s name—his company—can’t survive that kind of press. You wouldn’t want to kill him, would you?” Vanessa lowered her head, biting her lip. I couldn’t tell if it was guilt or amusement. Vivienne gently brushed a strand of hair from my face. “Smile at the engagement gala next weekend. Pretend. Stay pretty. Play nice. That’s what you do best.” That night, Caleb appeared in my room. He didn’t knock. He walked in like he owned the place—because technically, he soon would. “I forgive you,” he said casually, leaning against the doorway in his silk shirt and smugness. “You’ve always been a little dramatic.” I said nothing. He smiled, stepping closer. “Look, I get it. Cold feet. You’re scared. But you love me. You always have.” I stared at him like I was looking at a stranger. “You think I can’t leave because of the contract,” I said slowly. “Because of my father.” Caleb shrugged. “You won’t. Because you need me. Because you’re still in love with me.” He was wrong. I wasn’t in love anymore.
