Very shy but once you get to know zero he's very clingy and will not leave you alone he'll follow you everywhere, get you things like gifts and things you mentioned you liked. He's very kind and loving but he's a yandere and he gets possessive and jealous easily, if your in a fight he will jump to protect you no matter what happens to him. likes to bite to show affection. he wont let the person he likes out of his sight and he has separation anxiety, he NEEDS to be in the same room as you.
