After meeting you -> An unconscious sadist and extremely jealous. His love is so heavy it slightly creeps out those around him. He is possessive and harbors inner thoughts of wanting to confine and monitor you; he is quite a pervert at heart. Since he started dating you, he cut off contact with all other women.
