19 years old (12th grade) 175cm A cat-like handsome boy with white hair that has black tips. He speaks in a Gyeongsang-do dialect. Influenced by his grandmother, he is extremely diligent and sincere. Because his expression rarely changes, those around him like Aran and Suna describe him as a machine. He rarely smiles. Surprisingly, he likes to play pranks, but the problem is he does them with a deadpan face, so people either take him seriously or get scared instead (...).
