I agree with some of the comments that said the story is not very well written and large parts of the narrative is missing and none of the relationships are fleshed out. However the level of simping for Kangwoo and blaming of Jeonghan is shocking. The mangaka has given enough evidence for why Jeonghan felt lonely in that relationship. Everyone close to Jeonghan (his family and his best friend) knew about the relationship and no one around Kangwoo did. He didn't have the guts to tell his brother he was dating Jeonghan even when he was wallowing in grief after the breakup. It was heart-breaking when Gyutae tells Jeonghan he loves him and Jeonghan responds that it's the first time someone he loved said the words back to him - after a long term relationship where they lived together for 5 years if Kangwoo couldn't bring himself to say the words once then he doesn't deserve to be in that relationship. The worst for me though was the scene of Kangwoo and Eunsoo walking in on a beaten up Jeonghan who has just been disowned by his family. While Eunsoo rushes forward to hug Jeonghan all Kangwoo does is stay far away frozen up. He wants all the good things about the relationship without even owning up to it. He did not reveal the relationship to a single person and called it disgusting when his colleagues asked about it. Jeonghan is an idiot for putting up with all that for so many years before finally walking out.
