I have the best idea for a fanfiction but I don't know yet. I'll tell the story but I still don't know.

It's about a girl who's step-brother is Cho Kyuhyun from Super Junior and she falls in love with him  but he brings chick after chick home and she can't take it. Finally one day she barges in his room and confesses and they start a secret relationship but then her real older brother finds out and other stuffs happen but I don't want to ruin it anymore so yeah~ 

Yeah I know it's terrible :(
