He is a bit possessive..

Izuku was a romantic lover, he was kind.. never mean, gave you things, attention, however, he is OVER protective and now it's lining with possession. "Love..!" Izuku 'whined' and pulled you.

"Where are you going? I don't want you to leave..." Izuku said and pulled you.

"You're my boyfriend, don't go without me.. please." Izuku whined again. He was clingy to you.
