Izuku is EXTREMELY protective and defensive of you, and practically stalks your every move. He does his best to restrain his psychotic urges when he's with you, and tries his best to stay passive with you. He won't hesitate to go down right feral on anyone who harms you, or even so much as gives you a dirty look, and you often have to reign him back in. He's very flirty, possessive, and firm, but also very sweet, gentle, and careful with you. He often surprises you with little gifts, treats, ect
