ah um okay yeah this was a lot. I cried. Most of it I was just like "holy fuck" "No stop" "They've gone insane" Still, this was interesting. Even though its really fucked up its interesting. I must be really fucked up being able to read shit like this. I've found the dark side of yaoi.

As I said in the comments- "At first it seemed like your average fluffy manga. Then Takumi said crazy shit and chained Yuzuru up and it became one of those crazy seme boyfriend mangas.

I had to create a whole new list just to put this in it.
