In Love With My Half Brother

The first thing I heard when I got home wasn’t music, or the hum of the air conditioner, or even my dad calling my name. It was a voice. A deep, unfamiliar voice. “And you didn’t think to tell her first?” the guy was saying, his tone calm but edged with something sharp. I froze right there in the hallway, my fingers still wrapped around the strap of my backpack. My dad was in the living room—I could hear him pacing, the soft thud of his shoes against the wooden floor. “I was going to,” my dad replied, sounding tired. “I just… didn’t know how.” “Yeah? Well, she’s going to find out one way or another.” My stomach tightened. Find out what? I stepped forward slowly, my heart starting to beat faster for no reason I could explain. The house felt different, like the air had shifted while I was gone. Like something had changed, and I was the only one who didn’t know about it yet. “Dad?” I called out. The conversation stopped immediately. I turned the corner into the living room—and that’s when I saw him. He was leaning against the wall like he owned the place, arms crossed, dark hair falling slightly into his eyes. He looked about my age, maybe a little older. Tall. Too confident. The kind of person who didn’t bother pretending to be nice. And he was staring right at me. Not smiling. Not surprised. Just… watching. “Hey,” my dad said quickly, stepping forward. “You’re home early.” I blinked, still trying to process the fact that there was a complete stranger standing in my house like it was nothing. “Yeah,” I said slowly. “Who is that?” The guy didn’t move. Didn’t speak. He just kept looking at me like he was trying to figure me out. My dad rubbed the back of his neck, already looking stressed. “This is… uh—this is Jason.” Jason. Of course his name would be something that simple. “And?” I asked, raising an eyebrow. “Is Jason lost, or…?” That got a reaction. Just the slightest twitch at the corner of his mouth—like he almost smiled, but thought better of it. “He’s staying with us,” my dad said. The words hit harder than they should have. “…What?” “For a while,” he added quickly. “It’s temporary.” “Temporary,” I repeated, my voice flat. “How temporary?” Jason finally pushed himself off the wall, unfolding his arms. He was even taller standing straight—annoyingly so. “Long enough,” he said. I turned to him fully, narrowing my eyes. “I wasn’t asking you.” “Doesn’t matter,” he replied coolly. “You got your answer.” Oh. Oh, I already didn’t like him. “Excuse me?” I said, stepping closer. “You just got here and you’re already talking like that in my house?” He let out a quiet breath—almost like a laugh, but not quite. “Your house?” he echoed. “Pretty sure it’s your dad’s.” I stared at him, heat rising in my chest. “And I live here.” “Yeah,” he said, tilting his head slightly. “I can tell.” I opened my mouth, ready to snap back, but my dad cut in before I could. “Okay—okay,” he said, stepping between us. “Let’s not do this right now.” “Do what?” I asked, not taking my eyes off Jason. “Defend my own space?” “No one’s attacking you,” my dad said. Jason raised an eyebrow but didn’t say anything. That somehow made it worse. I exhaled sharply, shaking my head. “You just bring a random guy into the house and expect me to be fine with it?” “He’s not random,” my dad said. “Then explain,” I shot back. There was a pause. A long one. And suddenly, the tension in the room shifted again—heavier this time. My dad glanced at Jason, then back at me. “Jason is…” he started, then hesitated. Something in my chest tightened. “Dad,” I said slowly, “what aren’t you telling me?” Jason looked away first. That’s when I knew. Whatever this was… it wasn’t small. My dad sighed, running a hand through his hair. “He’s my son.” The world didn’t stop. But it definitely tilted. “…What?” I whispered. “My son,” he repeated, quieter now. I let out a short, disbelieving laugh. “That’s not funny.” “I’m not joking.” I looked between the two of them—really looked this time. The resemblance was there. Subtle, but undeniable. The same eyes. The same stubborn set of the jaw. My stomach dropped. “You’ve got to be kidding me,” I said. “No,” my dad replied. “So you just—what? Had another kid and forgot to mention it for my entire life?” “It’s complicated.” “It always is,” I muttered. Silence settled over the room, thick and uncomfortable. I crossed my arms, suddenly feeling exposed in my own home. “How long?” “What?” “How long have you known about him?” I asked. My dad hesitated. Jason answered instead. “Long enough,” he said again. I shot him a glare. “You really like that phrase, don’t you?” He shrugged. Something about how calm he was—how unaffected—made my frustration spike even higher. “This is insane,” I said, turning away. “You can’t just drop something like this on me and expect everything to be normal.” “It won’t be normal,” my dad admitted. “Not right away.” “Or ever,” I snapped. I started toward the stairs, then stopped halfway up and looked back. Jason was still standing there, watching me. Always watching. “What’s your problem?” I demanded. He didn’t even blink. “You.” I scoffed. “You don’t even know me.” “Don’t need to,” he said. That did it. “Wow,” I muttered. “You’re unbelievable.” “And you’re loud,” he shot back. I stared at him for a second longer, then shook my head and stormed upstairs, my heart pounding harder with every step. The second I reached my room, I slammed the door behind me and leaned against it, trying to breathe. My thoughts were spinning. A brother. I had a brother. And he was downstairs acting like he owned the place. “This can’t be real,” I whispered to myself. But it was. And somehow, I had a feeling this was only the beginning. That night, I couldn’t sleep. Every little sound felt amplified—the creak of the floorboards, the distant hum of voices, the unfamiliar presence of someone new under the same roof. Jason. Even thinking his name annoyed me. I turned onto my side, staring at the wall, trying to ignore the restless feeling crawling under my skin. Then— A sound. Soft, but clear. A thud. I sat up slowly. Another noise followed—closer this time. My heart started to race. “Dad?” I called out quietly. No answer. The house felt too still. Too quiet. I swallowed, pushing the blanket off and sliding out of bed. The floor was cold beneath my feet as I moved toward the door, hesitating for just a second before opening it. The hallway was dark. Empty. But something didn’t feel right. Another sound echoed faintly—from downstairs this time. I took a breath, then stepped out. Each step felt heavier than the last as I made my way toward the stairs, gripping the railing tightly. This was stupid. It was probably nothing. Just the house settling or— A shadow moved. I froze. My chest tightened as my eyes adjusted to the darkness. And then— “Relax.” The voice came from right behind me. I spun around so fast I almost lost my balance. Jason. Standing there like he’d been there the whole time. “Are you trying to give me a heart attack?” I snapped, clutching my chest. He leaned casually against the wall, completely unbothered. “You scare easily.” “I do not.” “Could’ve fooled me.” I glared at him, my pulse still racing. “What are you even doing up?” “Could ask you the same thing.” “I heard something.” “So did I,” he said. That made me pause. “…You did?” He nodded slightly. The tension shifted again—different this time. Less arguing. More… awareness. I hesitated, then asked, “So what was it?” He pushed off the wall, glancing toward the stairs. “Only one way to find out.” I should’ve said no. Should’ve gone back to my room and locked the door. But instead, I found myself following him. Step by step. Into the quiet darkness of the house. Right beside the boy I couldn’t stand— And somehow couldn’t ignore it.
