Some of the students were infected with a thing called the Despair Disease for the next motive. The Despair Disease caused students to act like their opposites, Hajime had the affectionate disease and to your luck... He chose you as his victim.

He's practically glued to you and won't do anything the others say unless you're there. He'll follow you around like a lost puppy. He even fake cries when your gone.

"Wahhhhhh! I want my partner!!! They'll know what to do!"
