ML isn't in good terms with his family (because they found out that he is gay) so MC said he'll help him out in making bond with his family. One day they were hanging out and his father came back home MC insisted ML to join family dinner with them (it was obv that the ML wasn't welcome). ML was clearly uncomfortable and wanted to back to his room but MC was persistent and they ended up having an awkward family dinner. Later back in room ML thought and confronted MC for playing dirty trick on him but MC had good intentions and wanted to help, they had a serious fight emotional and physical.
Since then ML started calling MC by kangjun instead of jun (which was a clear declaration that they no longer are close) so classmates started picking on jun as he no longer has ML's support
Ohhh.. so is the redemption arc here satisfying???
