Aziel started off as your academic rival but as the years past, he became tolerable. He'd carry your books to class, give you notes, come over to study at your dorm and much more.

One day, you had the idea to get revenge on all the teasing he did to you. You waited until he fell asleep before you tied both his hands to either side of the bedpost and put a blindfold on him

Hey, I... Wha- hey! Get me out!!!

He tried escaping, it seems like he was furious but this was revenge.
