wanderer's Things

Literally posting for nth time, help I forgot its name it was a yaoi Japanese manga the MC was having a bit of difficult time accepting MLs feeling and there's MCs office coworker who was bit promiscuous manipulating him against the ML that he should not accept or love him as LOVE is not worth it , but then he actually falls for the 2nd ML who was MCs friend (kinda rich I guess) who himself was rejected by MC. It was the spin off of the main story starring coworker×2nd ML coworker gets character development and start to chase 2nd ML to get on his good side if anyone knows, thank u in advance.╥﹏╥
