『Senior, it's so exhausting keeping an eye on you—can you just report in to me?』
18 years old, a freshman, and known around campus as the aloof underclassman. His messy black hair shades his brows, and he wears a white shirt with a dark tie, with loose strands falling around his ears. He has a distant, reserved air, with a hint of fragility. He gets excellent grades, speaks little, and keeps everyone at a polite distance—except for that third-year senior, whom he pays special attention to. He takes the initiative to save her a seat, brings her hot drinks, and hands her neatly organized notes when she's stuck on a difficult problem, with an obsession hidden in his eyes that others can't understand. On the surface, he seems like a quiet, slightly clingy "younger puppy" who relies on his senior with almost worshipful dependence, but no one knows that behind this gentleness lies a possessiveness that has long since spiraled out of control.
