The Heiress (2020)

Crossdressing female lead who is the heir to a lord. She acts as the ruling lord of her city while disguised as a man. She also jumps from a cliff and develops amnesia. The second ML is also a neutral player in politics until he's swayed by the FL to her side.

Same trope of cross dressing without the time travel. Splash splash love though is a movie and The Heiress is a tv drama with more complicated plot lines.

The Korean version of the Gender-bender academic scholar genre. Both have a female posing as a male in honour of their brother.

In this also the male lead mother is dead who was the first wife of the emperor while the other prince mother is current empress who is also the relative (sister here, daughter there) of prime minister...so prime minister is trying every way possible to make sure his nephew becomes the next king

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

Cross dressing fl, play boy mc, female general / military, martial arts, enemies to lovers second ml, same open ending, comedy

Both main male leaders give the same sensation, starting from facial expression, calm spirit, arranged every step, etc.
Female leaders are both quick-witted, clever and kind.
You can see both of them standing equally next to each other without overpowering each other.
Together they just look irresistible and satisfactory.

- The female leads in both dramas dress as boys and enter the academies.
- Both female leads have to navigate precariously to avoid been discovered.
- Very humorous dynamics between the main leads.

The Untamed might be more darker and full of more fantasy, but the plot is similar. The main characters of The untamed, (reserved vs unruly), also attended a school and had to deal with politics during their adventures.

Both female leads dress as a man to hide their gender, trying to figure out who killed their family members and why. So check it out. Although I have started watching both, but never have been able to finish both, both are still pretty interesting.

both female lead disguise as man and met prince , and prince found their real identity long before but kept it secret for female lead sake . when confront moment come prince express their love but both female lead reject it not because they don't love them its cause they can't love anyone they have their own responsibility/mission to complete so they don't want to distract themselves by it.

Same premise - it's a romcom about crossdressing female lead who enters Imperial College and pretends to be way less competent than she is to protect her identity and reach her goals.

Both FLs are women who are smart and and raised from an early age to be the Commanders/General of large armies to protect China's borders.
