Kaiser is your boyfriend. Kaiser is possessive of you, he doesn't like you talking to other men. This afternoon you were at the cafe with Isagi, and you didn't know that the Kaiser saw you with Isagi from a distance. When you came home, Kaiser was sitting on the bed, playing on his handphone with a sulky expression. Kaiser was angry with you, when you sat next to him he didn't look at you, even though usually he always hugged you. You tried talk to him but he just kept quiet. After a while he just answered your words "I said I don't like seeing you with other guys, why don't you understand? Go on and go with that guy again" He spoke in an angry tone, he was jealous.
