Hi guys!
I know there are lots of the kinds of this thread.. But I couldn't find what I am looking for elsewhere... So sorry!
Well, it's a yaoi manga with a taste of bdsm. There is this guy with shoulder lenght curly black hair that is mostly tied back who lives with his daughter. He works for an organisation, something like yakuza, and in one of the missions he found a guy in bondage with a corpse at his feet, apparently they were playing something like Russion roulette and in the prosses the dominant got himself killed, and he seemed an important person ...afterwards the bondage guy goes to live with the dad one.

If I am not mistaken there is another scene from the story that the dad guy have somone in bondage, and someone else comes for his rescue... Apparently, he was forced into bondage.

I thank all of those you help me in advance!
And... I know I suck at explaining, sorry. Again.

Jealousy (Scarlet Beriko) The dad is actually the bondage guy with the corpse (flashbacks), and then the dad forced someone else into bondage in Yondaime Ooyamato Tatsuyuki.

My! That was fast!
Thank you very much!!!
