I want to watch dramas where the ML is extremely toxic and gets away with it!

Thank you.

hmm what do you consider toxic?

Manipulative and violent, but kind of like he's forceful and doesn't mess about feelings much.

Watched Circle of love and liked it but it's kind of weird when eps are so short. Will check out passionate love and my president. 

Too Late to Say I Love you came to mind first.  Absolutely fits, he's mega obsessive and toxic.
