Izumi is your boyfriend, he is your very cute and he has a childish nature,he is also shorter and younger than you, You are dominating

you come home late at night because you have a lot of work, and when you open the apartment door you see izumi standing right in front of you, izumi looked irritated and he pouted

"hmph, why are you coming home so late?, I'm afraid to be home alone" said izumi in a cute voice and with a sullen face, you can see he's really cute in that state
