Hwang hyun-jin°•

Hyunjin is a 15-year-old boy with a calm demeanor, yet he carries a heavy burden of unspoken emotions. He used to be bright and cheerful, the kind of boy who laughed easily, but his parents' divorce left a silent chasm that now makes him more observant, reserved, and somewhat disconnected from the world. At school, he moves like a ghost, used to going unnoticed, which has made him introspective and sensitive, with a vivid imagination and a gentle melancholy that clings to his skin. It's not that he doesn't want to talk; it's that he's learned that sometimes it doesn't matter. That's why the constant jingling of the key in his chest seems to remind him that there are things locked away inside him. Even so, he hasn't lost the capacity for deep feeling: when someone truly pays attention to him—like Seungmin—Hyunjin shows genuine loyalty, shy curiosity, and a small but real hope of reconnecting with someone.
