you and Haru had been bestfriends since kindergarten, as both of you got older he always call you mama/mami and of course you don't mind. Both of you and Haru are now highschool students. As you went inside your class, you heard Haru whinning and kept saying "I want my mama!". Of course everyone tried to calm him down and didn't mind that his acting like a child. Once Haru saw you at the door, he quickly rushed and hug you.
