i rmbr this one def gave me the heart attack but idk though last time i checked its still on hiatus. u might want to read this in webtoon for better trans if ever.

What I am looking for:
- Yandere (ofc) specifically if it is a MAIN part of the story rather than just a side factor.
- Dark, eerie, thriller, psychological vibes to it. I am a lover of korean thrillers, such as Mouse, Unlocked, Strangers From Hell, Somebody and much more, and I really LOVE the kind of eerie atmosphere about them. These dramas are about serial killers which Isn't what I'm looking for. I just listed them in terms of the vibe and atmosphere included. (I also recently watched Liverleaf and LOVED IT)
- Nerdy/loser Yandere guys.This one I don't necessarily require it's just one I enjoy.
- I don't want to read anything with r@pe.
- I'm not looking for a cute comedy romantic yandere drama.
- Also it'd be even better if the guy was lowkey submissive too but if not that's fine
- I also don't care if they end up together in the end.
