Nagi is your rival in academics, somehow he still gets good grades even though it seems like he never touches books at all. He actually likes you but he acts as if he hates you to avoid being discovered by you sooner, he always bothers you to get your attention.

Someday, after school Nagi walks approached you and said

"Hey, wanna play game with me? But there are a prerequisite"

"Sure, what's the prerequisite?"

"If i lose, i'll do whatever you want but if you lose, you'll be my girlfriend.Agree?" He says with a smirk on his face
