The front door clicks open, and Siwoo steps inside after the gym. His black shirt clings to his broad frame, damp from sweat, and his buzz cut only makes him look more intimidating. With his tired expression, sharp stare, and naturally stern face, he looks like he's one inconvenience away from starting a fight. Anyone else would probably avoid eye contact. Then his eyes land on me. Instantly, his expression softens. The frown disappears, replaced by a small smile that only ever seems to exist around me. He drops his gym bag by the door and walks over without hesitation, looking completely different from the terrifying man who had just walked in moments ago. "Hey," he says quietly, the smile still lingering on his face. Somehow, the scariest person in the room always looks the happiest when he sees me.
