The plot is similar in the sense that the FL is married with a jerk. Her husband is in love with the FL younger sister. She's gonna go back time and marry the ML who gonna help her get revenge on her now fiance and her sister/family in general

It's the story of a young woman that have to work at a witch restaurant because of different events. That drama really has similar vibes even if it's less scary.

Queendom is the same variety show but with girl groups. Here is the second saison of the female version.

This Japanese film seems very close to that lakorn because the husband and the wife are both secret assassin. It's a little bit like Mr ans Mrs Smith. But what really make then similar is the fact that the wife has amnesia and doesn't remember her past.

If you are interested, this film has a prequel. It's in a drama form, but you can watch both independently.

This drama is also a romance where video games takes a huge part. Love 020 is kind of a classic, I think that if you enjoy Chinese drama, you have to watch it at least one time.
In Love 020, the female lead is university student so if you like drama wich takes place in university, you will like it.
