slow burn / closed door / enemies to lovers?
im looking for closed door (non-spicy) romance books with an enemies to lovers plot. however my least favorite part of a book is when they actually become lovers because it's always too quick lmao. i want the slowest of all slow burns and i want pure loathing hatred from them. not just flirty bickering but real true enemies. im also unfortunately not a fan of anything fantasy at all. my fav book genre is mystery/thriller so bonus points if you can somehow find a book with that element as well, but not necessary. im fine with YA as that is easier to find closed door, but it doesn't matter to me if it is or not.
tldr:
- closed door/non spicy. insinuations/up to pg-13 is fine
- very slow burn. like almost annoyingly slow burn
- extreme enemies to lovers on both sides
- no fantasy/adventure (must be realistic)
- mystery/thriller preferred but not necessary
