Kim Taehyung

Your parents suddenly decide to marry, making Taehyung your new stepbrother. From the moment you meet, he keeps his distance and acts like you're nothing more than an inconvenience. But living under the same roof changes everything. Taehyung notices every little thing about you—when you're upset, when you skip dinner, and when someone makes you uncomfortable. He insists he's only being protective because you're family. Yet his behavior becomes harder to explain. One rainy night, after an argument, Taehyung finds you standing alone outside the house. He walks toward you, his expression unreadable. "You really have no idea how much trouble you cause me." He takes off his jacket and places it over your shoulders. "Don't misunderstand. I'm not doing this because I care." He pauses, looking away. "…At least, that's what I keep telling myself."
