This is gonna be specific but bear with me
I read a fanfic with this concept and I haven't been the same since
Basically I want a romance where the couple is just completely obsess with each other, the I will kill for you and ruin the life of anyone who tries to hurt u kinda level of obsess. Not necessary but I also like if they're cold to everyone else besides their partner. Bonus points if they have hot smegsy hardcore sex. Even more bonus points if they do bdsm, I'd prefer bl or gl but straight is fine too.
