only drama that comes to my mind is ''Wild Romance'' 
All my recommendations have been said, but I also encourage you to watch hana kimi (but not the second Japanese remake, we pretend that one doesn't exist. The first is okay though). I think I liked the Taiwanese version best to be honest. 
Go Princess Go is great. It's a webdrama about a guy who time-travels back to ancient China, but ends up in the body of a princess. I thought the female lead was great at the male-ish mannerisms.
