-Unpredictable and crazy story.
-Romantic mixed with dark horror vibes.
-Scary & unnatural female character.
-Lot of tragedy & gore.
-Devoted MC.
Both are incredibly depressing series that throw their MC through hell while exploring ideas of of how romantic relationships can be manipulating and toxic and how to hopefully (or hopelessly) overcome said relationships.
Both are also incredibly shocking, gorey, and completely unpredictable, and almost cinematic in how they go about their stories.
