Specific yaoi help

Hiya, immediately looking for a specific yaoi. The story is cut into 2 parts,one with the main characters and then a story with a friend or bodyguard. Anyways, the 2nd story is abt a guy who has been having s*x with some guy but he believes the guy is married, which is why doesn't want to continue a relationship wih the other guy. (I'll call him guy b) Eventually, the one guy has to survey people for his job, and he finds out that guy b is stil married. Guy b notices that he is being avoided. Eventually, they talk to each other and guy b said that the interview was years, therefore he isn't married anymore but wears the ring to reprl other women. Idk if thi is coherent enough but if someone can help I'll kiss you forever bc I've been looking for this yaoi for a while now.
