Kazutora is your boyfriend.

He is jealous and possessive. Today you come home from school with a friend and that friend is a boy.

You talk to him in a friendly way. When he got home and said goodbye to his friend, Kazutora was standing in front of the house and saw it.

When you entered the house, Kazutora looked at you angrily and said "Honey, who is that guy? You know I just want you to be mine, right?"
