If you liked Love in the Moonlight, try Ashi Girl! They both have some similar themes:
- Girl disguised as a boy
- Historical + Royal Palace setting
- Hot prince!!!!!!
- Political Intrigue
- Romance??? I won't spoil it ;)
Also Mendol and Ikemen Desu Ne are some classic "girl in disguise" jdramas that both focus on the entertainment industry! Ikemen Desu Ne was my first ever jdrama and I loved it <3
Hopefully at least 1 of these 3 will interest you! Happy watching!
