K-Drama 
If you loved "Love in Disguise" , you really need to give "Bromance" a try because the two dramas have so many similarities. Both have a badass FML who can absolutely throw hands, a female lead disguising herself as a man, and that whole “wait… why am I starting to catch feelings for someone I think is a guy?” situation. You’ve got the protective ML, chaotic situations, secret identities, hilarious misunderstandings, and that slow-burn chemistry that makes you want to scream at the screen. Obviously, the stories aren’t exactly the same, but if you enjoyed the gender disguise, badass FML n chaotic romance vibe, Bromance definitely gives you that same feeling.
Years later, Dam I, the twin daughter, returns to the palace as a maid. After her brother, Lee Hwi, dies in a case of mistaken identity, their mother persuades Dam I to assume his identity. As she keeps her distance from others, Dam I begins to develop feelings for Jung Ji Un, her first love and later her teacher from a noble family.
