can some one pease suggest manga with possesive and obbsesed ml straight with adult romanc...

Here are some really good hetero romance manga/manhwa with possessive or obsessive male leads:

Betrayal of Dignity – very intense, controlling and obsessive male lead with strong psychological tension.

Dreaming Freedom – modern setting, toxic but addictive possessive male lead.

The Broken Ring: This Marriage Will Fail Anyway – cold but deeply fixated male lead, political marriage drama.

I Swear I Won’t Bother You Again! – more emotional obsession, regression story.

The Villainess and the Demon Knight – fantasy romance with a very protective and possessive male lead.

I hope this helps! (⌒▽⌒)
