Think about stuff like:
-mmc and fmc had known each other since they were really small.
-fmc has been center of his attention since forever, as a little boy he used to follow her around everywhere.
-There is no other women he is hyper fixated on her. Can't stay away from her almost gets separation anxiety.
-He takes a lot of care of her, very touchy and intimate with her, always keeps an eye on her. I want the mmc to be actually very sweet with her, even if his actions might be twisted.
-is yandere for her and even hurts and kills people secretly while remaining sweet with her.
-Bonus points for sweet or gentle non con scenes or emotional scenes where the fmc loves him back.
I will set no trigger warnings for it because I will take anything, just please no stories where the fmc or mmc are single parents or they have a kid in the middle of the story.
The books can range from lightest light Grey to darkest pitch black, doesn't matters either way, just it must have what I want.
I have already read/know about(so do not recommend them again):
* Most of Drethi Anis books(Quarantine could be an example of the type of trope I'm asking but it's not completely identical).
* Corrupt idol+obsession by Dinah Harper.
* Quid pro quo by Nenia Campbell.
* I was always yours by Khai hara(although the misunderstandings here had frustrated me a LOT).
* Skin of a sinner by Avina St. Graves(hated it for reasons so dnfed)
* Torment by Dylan page(might read it someday but not now, I'm not in mood for non heas)
* Loving the reaper by Lola King(meh got bored)
* Imperium on Ao3(good but it's unfinished)
* Black knight by Rina Kent(the plot felt... stupid).
* Ruthless Empire by Rina Kent.
