Kai is the one of the most popular guys in school.
Part of both the basketball and baseball team, it's not a surprise any girl would kill to be his.
So, of course anyone would say yes if he asked them to prom.
Except the boy his friends had picked out.
No, that boy was a challenge.
And he can't say no to a challenge.

Do Kyungsoo is a simple boy.
He did what he was told, got good grades and kept his two friends out of trouble.
He didn't go to sporting events, or any school festival.
So why the hell is Kim Jongin following him everywhere he goes?
