People change. People can like someone now but not before. He was childish before. He was pretentious. He's showing sincerity now so sit down and understand that people can be different from how they were when they're young. Yes, i'm also upset for MC's situation and how he felt but Yoonseul was literally young before. He's been straight his whole life what did you expect? For him to instantly like him??? Lmaooo
