Comparable vibes.
Both are "spy novel" dramas where secrecy is key.
Secret organizations, check.
Brainwashed organization members, check.
FL leads are great fighters, check.

both have:
- favored general that holds much military power
- the general is feared and considered a dark knight
- arranged marriage by order of the emperor
- unwanted marriage by the FL (and her family)
- emperor favors the general
- hidden political plots

Not a gender-bender or time-travel. But in similar manner there are fake identity crown princesses, Mr. Queen is a man from the future inhabiting the crown princesses body, in Fake Princess the crown princess is a look-a-like that gets swapped in for the real crown princess.

In both stories the ML (crown prince) is suspicious of the FL (crown princess) as she comes from the "enemy camp". Also in both stories the ML (crown prince) is also under threat from enemies all around him and must behave low-key and plot secretly with few allies.

The stories are quite similar, romantic and funny with a more serious undertone, fight scenes, plotting, and mostly the pull and push relationship between the ML and FL where they battle suspicion and romance between each other.

Light and fluffy comedies that are easy to watch. Silly comical but energetic FL with cold (on the surface) ML. Similar historical setting, but no god realm characters. But plenty of fighting scenes to give you some action dosage.

Both light and fluffy dramas, romance and comedy, with a cute and lovable leads. Both not very heavy dramas, easy to watch and with unique stories.

- Forced entanglement
- ML and FL dislike each other
- Fierce FL that detests ML
- ML needs FL because of appearance or because of business
- Relationship agreement of sorts
- No cohabitation though
- Same director

- Fierce first contact between FL and ML
- FL dislikes ML
- Down on her luck female lead
- Cohabitation
- Incidentally forced entanglement
- Gets attached to male lead
- Female lead a strange heroine
- Male lead with a shrouded past
- But difference is idol drama vs lawyer drama, not similar genres, but similar vibe

Although not a body swapping thing, it does involve a high school girl going to the past to Joseon time and becoming a eunuch because of a misunderstanding, is put to work directly for the king and the two fall in love. It does involve water as a medium of time travel, both series have that. It also has the FL trying to help the ML to rule as a wiser king, both series have that. And in both series the king becomes a influential ruler that affected korean history because of it. And instead of bringing culinary skills to the past, she brings modern day math and science knowledge.
