kei is your academic rival. he was always 1st while you were 2nd. you obviously hated being second. one day you were at the library studying your notes when someone sat beside you.

when you looked up to look who it was, it was kei. you didn't bother to look at him nor talk to him since you were having trouble with this one math problem. until..

"thats so easy" he said as he took your pen and paper as he easily and effortlessly wrote and solved the math problem leaving you speechless.
