Bad guy-revenge
Similar to monstar (music): Dream High-two movies, personally I prefer the first one, which was played by Kim Soo Hyun. It was quite good, the music was excellent, and the first love was bleak.
How about it-it's also a musical, but it's just so-so. In order to succeed, the result is not the protagonist.
You are crazy about me-tolerance, the theme song of the same name is very popular.
Similar to kpop's deadliest battle (disguised as a man): Sungkyunkwan gossip-the ancient F4+ comedy Liang Zhu, which is very interesting.
To the beautiful you-dress up as a man and go to a boys' school.
"My Boy"-disguised as a man, a novel theme, disguised as a woman is ok, modern, only three episodes.
Paris, a nail salon-quite strange setting, not very beautiful, disguised as a man to get writing materials from the nail salon.
