I have been searching for Korean dramas with the genre romance and comedy. I would prefer modern ones (meaning, please don't suggest dramas with settings related to the earlier/old years where dynasties happened), and if possible, the setting is in high school, college, or show business. Also, if you know any other gender bender Korean dramas (wherein a girl/woman pretends to be guy <I prefer only that and not the 'boy-to-girl' types> ), please also suggest that.

So far, I have watch the following korean dramas (so please don't suggest it anymore):
Coffee Prince, You're Beautiful, K-Pop: The Ultimate Audition, Heartstrings, Mischievous Kiss, Dream High, Ouran High School Host Club (live action).

Thank you
