I'm in the mood for watching a romance drama where the leads are in a toxic relationship with each other. Something along the lines of Love Syndrome III

*toxic NOT one-sidedly abusive where the other person is a doormat

*strictly no cheating

* leads to end up together

*any country but with subs, fine with BL too

*dramas after 2010 preferred

Thanks in advance!

the problem is....most dramas with a toxic relationship (where both are toxic to one another) don't truly end on a happy note. There is  Kleun Cheewit but he is more toxic to her than she is to him here. Same thing with Cunning Single Lady. But here the couples end up together in the end.

There are a lot though with one character being happy eg. Somebody .
Th same can be said about toxic relationships in regards to cheating. Most have some sort of cheating theme going on like eg. Before we get married or Graceful friends.

Possibly Time Flies and You are Here? Both leads can be pretty terrible to each other (although ML more so), and the leads end up together in the end.

And I don't know if everyone would consider it toxic, but Koi to Dangan has a unhealthy relationship between the leads (both are possessive, obsessive, and reckless).
