Hello!

Can you help me once again to find a yaoi manga?It's a very heavy story about a yakuza member who was sent to jail, I don't remember if he had committed a crime or if he was covering someone higher in hierarchy.He was living with at least 5 more inmates and they were all sleeping on the floor.One of the inmates was a yakuza member too and his "lover" was a young boy and i remember that they were having sex while the others inmates were sleeping and somehow the boy made an eye contact with the new comer and eventually came on to him but he turned him down.I don't remember how exactly they got together,I think that after he got out of jail the boy looked for him and they gradually became a couple, but when the ex lover was released from prison, he tried to get the boy back and take revenge from the guy who stole his lover.I know I'm missing or might be wrong for some parts of the story but I remember that although the story was heavy ,intense and sometimes uncomfortable,it had a happy ending.I would love to read it again, I know I can count on you guys, thanks in advance.
