can someone help me find this manga (sorry for the long description)

ok so i read this manga when i first found this site but it was ongoing and now i cant remember the name it was about a business man who's not very liked at his company because he was in charge of firing a bunch of people so all his coworkers avoid him and he gets a lot of hate from the families of the people he had to fire, and there's this very flirty masseur at the company he works at and he usually avoids him because whenever being when there together he feels uncomfortable, but he come into work with a back injury one day and one of his coworkers (literally the only person at the company who want to be his friend) tells him to go see the masseur and he really has no choice but to go, now the masseur's being as flirty as ever and the massage starts to get a little intense, they have sex, and the masseur hangs this over the business mans head to convince him to keep having sex with him and turns out the masseur's dad was one of the people the business man fired and the masseur wants to make it so the business man cant live without him as revenge i guess. sorry the description was so long but if you know what this is please tell me the name because u cant find it anywhere Σ( ￣□￣||)
