Being the son of the boss of the biggest maffia gang in whole Seoul is really the worst thing.

Yiyun lives on hisself because he doesnt want to have anything to do with his father.

He gets bullied in school.

The only one in the school who likes him is Dr. Kim.

He is the schools doctor and because of Yiyun getting bullied he visits the nursery like everyday.

Will it ever change or does he has to suffer of this for the rest of his school life?
