Bromance (2015)

The series follows a fictional musician band, A.N.JELL, and the relationship between its members when a girl, posing as her twin brother, joins the band.

Gender Bending because of family obligations and responsibilities.

Gender Bending because of family obligations and responsibilities. The female lead also knows martial arts and is chivalrous. She is strong willed and confident, with many friends.

Both drama have gender bender romance with excellent casting choices for the fls. In both drama the fl had to hide her gender in order to survive(well not so much in one case but superstition is a peculiar thing) and becomes an aide to the ml. Bickering and falling in love kind of dramas

Gender Bending because her missing mother insisted that the female lead had to be a boy. Female lead is confident strong, witty and smart but she really wanted to be herself rather than 'himself'.

Historical setting.

Gender bender, cold guy who is a K-pop star and cute girl/guy who wants to be a singer. Def like Bromance.

Because of one simple word from a soothsayer, Pi Ya Nuo has been raised as a boy all her life. By chance, she saves underworld mob boss Du Zi Feng and his sister. His sister falls in love with Pi Ya Nuo at first sight. Things get complicated when she becomes "sworn brothers" with Du Zi Feng, just as her 26th birthday comes closer, and with it, her chance to finally live as a woman. As her 26th birthday approaches, she must decide if she wants to return to a woman or continue to be Du Zi Feng's best pal.

Both dramas have comedy and a female lead that must disguise as a male.
However, Bromance is set more in a business-like setting and does not contain fantasy (it just contains some fortune telling).

Female lead has to play it off that they’re a guy. Tough female lead who can fight and falls in love with a rich guy.

Same screenwriter - Shao Hui Ting. Both series are laugh out loud funny with adorable/loveable characters. Bromance is cross-gender-dressing and History is BL. If you liked Bromance, you
will like History!
