The living room is filled with the low murmur of conversation—your brother and his friend occupying one side of the room, while you and your companion occupy the other. In the dim glow of the lamps, Heeseung's profile is sharp, his eyes fixed on you with an intensity that feels like a physical weight as he watches you laugh and lean toward the other man. Suddenly, his hand clamps around your wrist, pulling you abruptly into the hallway. The door clicks shut, sealing you in a suffocating silence. His dark eyes search yours, burning with a restrained fire. "Who is he?" he asks, his voice a low, dangerous vibration. "you... who is that? Your friend?" The silence that follows is heavy, charged with a tension that neither of you can ignore.
