The first part is romance
but some manhwa has a bit of romance while others focus on the action. There are some that action and there are some with drama types of stuff like Roxana
2nd part is idol/acting
3rd is shounen

(youko from 12 Kingdoms)
(I recommend that you should watch twelve kingdoms too.. I don't think they have a manga though but there is an anime and novel.
Mc rules a kingdom and the readers get to see how much she improves from naive to strong women)
