This is absolutely amazing if you're into psychologically twisted and dark stories
I’m not spoiling this one since it’s really good but sister hear me out on this, the ml is ‘hot’ in the best way and she’s intimidating as shit too so buckle up because the mc somehow doesn’t want her seemingly lmao

The Haunted Mansion, it's 15 chapters, has vampires, generations of same guy (almost like reincarnation?), lots of smut but still romantic

Anyone have any psychological/ dark romance to recommend?? ^^
