Hi! 

I'm looking for Korean dramas that focus on kpop trainees. I know Dream High 2 had some flashbacks to JB's trainee life but I'd prefer dramas that are centered on it :) 

Thanks in advance ^^ 

This made me think of K-Pop - The Ultimate Audition, although I'd have to say that Dream High was way better. This drama also has some elements that remind me of You Are Beautiful as well because they're both gender bender kind of story. Enjoy :)
I don't remember that well but I'd say What's Up is one of the dramas that could fit the theme.
