Can someone spoil this for me I want to read it but I need spoilers

•Mc ended up with his coworker [short haired girl] and got married at the end [shitty ending]

•Girl that got cheated on tried to console with the MC but mc rejected her, was depressed for a while but found a gay friend that was with her throughout and found some happiness and looked healthy [she got the best ending tbh]

•We never heard anything from his brother after the ending
