Dramas recommendation with OBSESSIVE SML

I really want to watch a drama Where I would get to See a strong love triangle where 2 guys fall fall for same girl. But I don't want to watch.Regular one where the SML Is just shown as a side character And over a period of time he gives up This time I want to watch intense were the SML Is very obsessive and possessive To get the FL HEcan also be villain and features dark romance or psychoness towardness FL He just doesn't gives up and constantly purse AND Try to get her strongly rivals to ML .   Where simultaneously the ML IS ALSO DASHING AND POSSESSIVE. It's just something which I want to see where both of the leads ML AND SML Are insanely love with FL And Neither of them backdowns In attempts of getting her and strongly compete with each other. It should also be very intense and dark romance.  Some indian and pakistani dramas which I watched were HAASIL and EK dewanna Tha were my favorite also available in eng sub on youtube . I also enjoyed khaani and summer desire. Guys, please recommend me such type of drama.I don't Care, which country but I want to see this dynamics?

Thanks
