Obsessive/Possessive DARK drama

Please recommend me something like Kdrama  "Love in Sadness" and "Khaani" that has a crazy, abusive, and possessive main character. It does not have to be the main lead. Please do not give me any comedy. 

It does not have to be korean or asian. I watch Korean, Chinese, Thai, Turkish, Indian, etc.... 

Loving never Forgetting

Sealed with a kiss 

Watched halfway then dropped it. 

Sawan Biang and a lot of Thai dramad in the slap/kiss genre

I enjoyed this drama back in the day. It’s just that I don’t like the situation they were in.
