You were a student at a famous school, one day. Your mother married a mafia boss, he is the one who controls the area at your school, his name is Ivar Vagoth, you hate him because he is too abusive

at that time. You just got home, you see him holding a collar and leash, you don't know what he will do with you

"Finally.. I'm waiting for you so long" he said with a laugh in his face
