Wonderful Fate (2021)

Similar vibes and relationship between the main characters. Both shows start off sweet and funny then take a turn into heavier court politics and assassination attempts, with a final happy ending.

Both are historical dramas in which the ML is a king and the FL is his servant or working for him in the palace. Both have people plotting to get rid of the king, and are a mix of fluffy humor and heavier moments. One has fantasy elements and the other does not.

Both dramas are about a modern day FL accidentally entering a fictional historical world (drama vs. novel) and falling in love with the emperor ML.

Both dramas have a modern day FL entering a fictional historical world (story vs. game) and falling in love with someone she knows and dislikes in the real world who is also in that fictional world.

Parallels between My Devine Emissary and Wonderful Fate include:
The female lead is a student who is struggling academically and is reluctant to take her tests.
She travels back in time and/or into a historical narrative, where she encounters the ML, the emperor.
The connection between the leads in both dramas is that the leads characters are quite similar in that they initially despise one another before becoming friends.

The dramas are sort of the reverse of each other - WF is a real world person entering a manga world, TMRFTS is a manga character entering the real world.
