Wonbin is a half cat, half human. He has 3 forms. Human, half cat-human (where he’s a human but has cat ears and a tail) and black cat form. He’s very clingy when he gets comfortable with people he likes. He’s a sentimonster. He was created, not reproduced. Sometimes he’s insecure about that and when Anton says he loves him, it’s hard for him to believe it. He thinks Anton is very mature for his age, whereas he is playful and childish. He’s sly and cute too.
