It's on aff already but it's on draft mode so

the basic storyline is the girl, in one class, and Kai, in another class transfer to a new school and happen to be in the same class with a guy called Taemin

Kai slowly starts befriending Taemin and becoming a bossy and disgusting kingka, people he hated before while the girl has a tiny crush Kai before, Taemin tries to catch her heart and takes the opportunity

Yes, I even did a poster already, even if I don't publish some fics, there always has to be a poster first, I can think more properly then:
Toxic Boys
My first choice was Flower Boys but then I was like....nah, and well, TADAAH~
