ML was adopted but not loved, MC was in love with the straight boss who got married so he was feeling heartbreak over it and the friend/coworker was telling him to get it together, get over it and congratulate boss properly, in that moment ML saw that happening and saw in mc someone capable of such strong love and it made him love mc and want his love directed at himself and started chasing him by going into architecture to cross paths someday
