Re Bu Qi De Qian Sui Daren (2022)

Both are light historical dramas in which the ML is after something and pretending to be a eunuch in order to accomplish his goals. Both FLs are free spirited.

Same leads. Ancient setting. Good chemistry. Even better kisses. Intriguing story development; never gets brought to resolution however. It’s as if there was originally intended to be a sequel, but the team just abandoned the project. There definitely needs to be a Season 2 because the last episode had a huge cliffhanger.

FL finds herself in an arranged marriage with the ML that turns into genuine love. The ML hides his true identity/personality behind a different persona (pretending to be a eunuch vs. pretending to be unintelligent).

The protagonists pretend to be a eunuch to enter the palace and investigate the truth behind...........

Both are historical dramas in which the MLs are pretending to be eunuchs in order to investigate a case. The FLs learn their secret.

Character pretends to be a eunuch (FL vs, ML) which causes confusions in other main character's feelings toward them. Mix of light and serious moments. Historical setting.

Both are light historical dramas in which the FL is forced to marry the ML who is pretending to be a eunuch. Despite a rocky start, both couples end up falling in love. Both dramas appear to be adaptations of the same novel.

Same actor as ML. Similar historical setting, tone, and relationship between the main couple.
................................

Both MLs are pretending to be eunuchs in order to achieve their goals. Both FLs discover their secret in the opening scene, so the ML ends up taking them to the palace/taking them to his home to protect his secret.

Both are historical dramas. Both MLs are fake eunuchs out for revenge who unexpectently end up living with the FL.

Both dramas have the ML with a false identity/secret that he uses to investigate an old case and find the truth about the past. FL is of lower status than the ML. Both are lighter dramas.

Both MLs have a false identity/secret and are married to the cheerful FL who is of lower social status. The main couple are initially indifferent to each other, but soon fall in love.

both have same male lead and female lead with short length drama under to 20-25 episodes . it will not be great but you can kill your time nicely with that stuff without hesitate. its fun to watch.
