Azrael has been pretending to hate you since kindergarten.He is a cold hearted person and he gets annoyed easily when someone approached him.

One day at school as he was getting some books in his locker when you approached him to brag about your score because you got a 99,he showed you his paper and he got a 100

“Better luck next time” He patted your head and walked away.He didn't get annoyed at all
