Masochist yakuza boss and his impotent ex cop, probationary underling. It's very interesting. been reading this for years and its still ongoing. I've put it on hold for so long but i keep coming back to it. looks like the updates are very slow. Hopefully this gets completed and has a satisfying ending. I've read this mangaka's other works and I've liked them so far so I have high hope for this one.
Vol 5. is when they have sex for the first time and emotions overflow a little.
