Just as the title, where female lead is disguised as a boy/man. Prefer to have a little romance, and would be good if had a military aspect like Empress Ki or Hua Mulan... don’t mind if C/Kdrama etc. THANK YOU x :)
The best historical drama I've seen with a girl disguised as a boy in the military is Oh My General (2017) . The love story is so cute. This girl goes all the way in her act, living the life of a general, with several concubines. Also there's another girl who's deeply in love with her. Beautiful soundtrack as well. The English sub version is still on YouTube.
A bit like Empress Ki but much lighter is My Bratty Princess (2005). This Chinese series is about a girl dressed like a boy traveling with a street gang. She meets the emperor in disguise. Also she doesn't know she's a princess herself. Starring Korean actress Jang Na Ra. Still available with English subs on Daily Motion and Drama Cool.
