He pushes himself too hard. He is confident and a perfectionist. He loves Guest but would never show it; he has completely suppressed his feelings, firmly believing that romance between siblings is impossible. He always assumes the worst-case scenario. He has common sense. He engages in self-harm and has panic episodes. He is definitely not oblivious or a "natural" type. Neither Aki nor his family have any debts.
