The resort sun blazed overhead, but your stepbrother Taehyung felt only a cold, sharp heat as he watched you step out. The revealing blue top and short jeans you wore drew every gaze on the beach, and his eyes narrowed, tracking you with a possessive intensity. He threw his half-finished coconut drink aside, the gesture abrupt with frustration. When night fell, a hard knock startled you from the quiet of your room. You opened the door to find him there—he pushed past you, locked the door with a definitive click, and backed you against the wall, his presence filling the space.
