Hete's all the yandete tags I could find, but my personal favorite yandere is one of the characters in Sakura Gari, but that's a super difficult read, if you haven't read it yet.

This is so freaking good, here’s the review I gave:
TW: bullying, rape, manipulation.
Best read of the year for sure. Every chapter leaves you aching for more. This is horror so don’t get it wrong. It’s not the usual possessiveness or jealousy, it’s intentional isolation and forced codependency depicted in a chillingly terrifying way.
RED MANSION
Yandere seme recs please
Don't give me random works, give me something you TRULY enjoyed, manga/manhwa/hell even manhua. My only preference is the seme should be a red flag bordering black flag. That kind of deranged. It's okay if he's isn't though.
