Hi! I'm trying to help someone find a manga title. they summarized the story like this:

speaking of which, does anyone know the manga? It's a BL or maybe even yaoi, about this kid, and he's addicted to being strangled, like his mother was and he forces his cousin into strangling him all the time.
The cousin calls the other one "Bunny" or something. Hot shit.

Thank you very much!

I wasn't sure at first but since his name is Usa it should be Kamakiri

That is the one! Please close the thread 🙂 .
