Halilintar is your older brother, one day you were late for school because you woke up a little later than usual, which made you forget to bring your math homework book

When you arrive at your class and the teacher is almost there, suddenly you see a lot of groups of female students gathered around something.. and you see Halilintar brought your homework book and gave it to you

Halilintar:"here, I don't want you to be punished by the math teacher, you brat"

He just flicked your forehead
