This drama was cute, sad and what is most important this show was for your own thoughts. You start think about how you look at other people. After watching this drama, you will realize how much damage can people make to others based on their looks.
Also I don't get why people hate Eun Woo. I really enjoyed his acting and when I hear people talk about his expressions, I wonder, why they don't say this about Song Kang. Don't mind me wrong way, I love Song Kang, that is why I am mentioning him, because he mostly plays characters like this and nobody says anything.
This type of characters are always tricky and I understand that many people won't get it, so maybe next time turn it off and don't throw hate on actors.
