Can someone recommend tragedy yaoi ??

10 years i loved you the most

I'm not sure to know what you mean by tragedy, but this one is pretty dark, rough and weird. You feel so bad for the main character and how his mind gets messed up. And it's really smutty as you can guess by the title

Juujun Bitch Lover (prequel) and Doronuma (sequel)

I second that!

It looks really good ! Thanks for the recommendation ヾ(☆▽☆)
