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.
I have read enough comments to say that NO ONE LIKED KANGWOO JEONGHAN AND HIS NEW LOVE INTEREST simply bc they're all trash: The first a coward, the second doesn't know how to communicate and the third is a rapist. All the comments are about how disgusting they found how jeonghan didn't root for better but instead choose another violent relationship, so yeah, the story just suck
Though the writer made a valiant attempt to rehabilitate him the writing had already disintegrated and he had made such a bad mess of things that both the story and the MC are unrecyclable trash. Before anything went wrong let's take a look at his behavior. He has a very close relationship with Jaemin who promises that when they grow older they will buy a house and live together. Jaemin tells him repeatedly that he is just waiting for him to get to college. Once he gets to college everyone and their mother knows Jaemin likes him but MC is somehow insecure. Jaemin makes a date with him on a Sunday saying "he has something important to say". What does the MC do? He flirts with Soohyun and kisses him. Accepts a ring from him. Gets drunk and goes to Soohyun's house barely days before the Sunday when Jaemin said he has something to say. Has sex with Soohyun and then goes to uni with the marks showing to meet Jaemin who has to button his collar for him. He does all this while claiming that he loves Jaemin who is left to hold the bag. Then he claims that Jaemin made him feel lonely by not confessing to him. Really? What part of him doting on you and saying in actual words that he wants to be together? Because he didn't rush to have sex with a school student? Because he waited? After wasting half a day reading this my only question is why are 3 perfectly good men so obsessively in love with such a trash. In my head-cannon he cheats on Seunghyun who eventually leaves him and MC ends up truly alone to face his demons in his dreams all by himself.
