I can understand why the MC acts the way he does, putting Yihan as his priority and keeps being oblivious to the toxic shit between them, but like, he should at least be friendly with Jinwoo, who helped the MC so much without him even knowing. "The one I love is already set in stone" says the MC, but he could at least be a normal fucking person and do the bare minimum that is replying to a simple text from Jinwoo... and if you truly loved Yihan you would not stand still as he gets married, even more so if he hid the fact he was already supposed to marry the girl all that time ago. Keeping secrets in a relationship is what destroys it, you should have trust in your partner, trust that he would accept and help you under any circunstances. Yihan was not honest in his relationship, and he never planned to be, even if he didn't end up marrying later on, it would still not work out as the secrets between them would pile up.
