because that bitch blackmailed kang jinha with siwon's and kang jinha's kissing photo and told him that he will show it to everyone in the school if he ever tell something about him
Why doesnt he just tell him, and then tell siwon to act like he doesnt know. I mean that is a he'll of a lot better than risking your relationship...
maybe he thought siwon wouldn't pretend like not to know him. but you're right being like this he already ruined everything （￣へ￣）
oh yeah now I remember ... that makes more sense .. thanks
you're welcome ヾ(❀╹◡╹)ﾉ~
am I missing something ? why doesn't Kang Jinha tell him who is that guy really is ?
