LF something like kim nana and seon woo

Looking for a couple like these two from monstar.

Well kim nana is seen to be a delinquent who is dating a gangster ( but are only rumors) so she is avoided most the time. She secretly likes Sun woo. As for Sun woo he is the class rep and is one of the few people who do not fear nana. He is responsible and really cool (the way he handles situations and is very talented in singing ) and likes another girl in the show.
