can someone find me the title of this yaoi

younger bro (seme) came back to their hometown bc their father died and older bro (black hair, uke) wants him to be the successor of the group. they're yakuza or something. younger bro is in love with his older bro and eventually found out they're not blood related at all. i kinda remember the older bro's name is somewhere along misaki?? the older bro was using someone in the group to make the younger bro back off (like showing him they're kissing and stuff) so yeah i think this is an old yaoi manga and i remember reading this a long time ago and the itch of not remembering the name is bothering me so much
