Binge-watched the first season. Very nice and smooth story telling. Excited to see continuation sequel.
Also I think Ha Doyoung will take part with his wife and he is going to help her to “get rid of” Moon Dongeun. He is acting like a good person but It’s obvious that he is a materialistic psycho too. I’m sure about it.
i think it's mostly because he was in depression because of the school stress and other reasons. he needed someone by his side but the girl that he loved choosed to say a thing like "we shouldnt be together until we go to university" so he thought that no one truly loves and needs him.
