You were having a peaceful life until...

One day, you confront a weird situation with your classmate. He is known to be a bit crazy around people, in general.

His name is Yin Yuji. He was having a loud argument in the middle of the class, in the early morning, not caring about the others. He was a stubborn person.

"Man, I don't care! You're not my dad!~ I can do whatever I want!"

He screamed. You appeared in front of the door, and unfortunately, you got the attention of Yin..
