Hi! I think this one manhwa fits your criteria

A lot of this authors works are yandere-ish and fucky but not violent.
My personal favorites are Colour recipe while it isn't violent it's really manipulative and mind fucky and ends with the reader knowing inevitably that the seme will get what he wants in the end despite failing his first attempt. Hikizuru Oto is another kind of fucky one where one kid guilt trips the other using his disablity into staying with him forever.
Yeah yeah that's the one that I said I forgot name. That's so beautifully written
Thanks I will check them out!
I want to read BL like Killing stalking. The necessary condition is 'leg breaking' . There are many BL/Yaois with semes saying 'i will break your legs if u run' but I never see they actually break them. I want to see seme actually breaking/hurting MC's legs like ks, sadistic beauty and smth I forgot name.
(If u r uncomfortable, pls scroll down. I just want to see some extrmem Yaoi to analyze smth for my books)
