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

If you’re looking for dramas with an intense second male lead (SML), I’d recommend ‘Secret’ or ‘Cheese in the Trap.’ Both feature SMLs with complex, obsessive tendencies that keep the story engaging. What are you looking for—romantic obsession, or something darker? Let me know so I can suggest more! When I was in my third year of university, I needed help writing my academic thesis. I started searching on Google and found that Domypaper had positive reviews on their website. I decided to use their service https://domypaper.com/ for my thesis, and it turned out to be very helpful. The thesis that Domypaper delivered was of high quality and easy to understand. They also offer essays, dissertations, research papers, and other writing services for their users.

I like this trope so I have a few dramas to recommend, but they're gonna be older. The 2ML is very possessive/obsessed in these.

Summer's Desire this one is exactly the type you're looking for. You'll even have a hard time knowing who is the ML. 

Discovery of Romance 

She Would Never Know 

2 ML acts like a bestie towards FL but is secretly obsessed with her

Bromance 

Fated to Love You 

Here to Heart 

I Have a Lover 

Cunning Single Lady 

Love Is Sweet 

Nothing But You 

Dramas with darker vibes, maybe the ML and/or 2ML is a bit (or a lot) scary

Cheese in the Trap 

Love in Sadness 

Maestra: Strings of Truth this one is not focused on romance, the leads are also older.

Missing You 

The Devil Punisher 

Queen of Tears 

Encounter
