Help! Can't find the manga

[Akhalhast]

For not so long ago I read a yaoi manga that I really liked! Now I want to read it again but can't remember the name and I can't find it anywhere so please, help me :(
It begins with that the main person is cheating on his boyfriend and gets dumped. The boyfriende then finds another guy whom is a yakuza (sort of). The mainperson starts to work for this yakuza guy who starts to take intresse in him. However, the mainperson rejects him 'cause he don't want to hurt his old boyfriende.. Or something like that... Does anyone knows which one I'm talking about? Please help :(
