http://www.mangago.zone/read-manga/yondaime_ooyamato_tatsuyuki/ is it this one?
Nope, I have this one at home lol
I read it a while back their the uke is the son of a yakuza but the seme t hought that the uke was a yakuzas boytoy
Yes yes sth like that! Dont you remember the title maybe? ;-;
I remember very little but one guy took the other home probably from street and I think the other one had a tattoo on his back so the first guy was worried that he took some yakuza's partner. The one from yakuza had long blond hair and I think he was actually an heir but I'm not sure?
I'm not sure whether it was whole manga about them or they were extra to sth
