I don't understand why people are hating it soo much. ok, so for me this was not a very bad drama. I liked it also upto some extent. a lot of people are saying that the heroine is putting up so less expressions,. guys, that is what her character is supposed to portray. so the storyline was pretty much normal. And one thing I really loved is that the heroine's love for her ex boyfriend remained constant and the same was for him. she may have shown that she was swayed because of the new student but that wasn't true. in fact the reason why she left and then came back and suddenly started asking for breakup was because she was pregnant and had a miscarriage. And the person who actually killed in ha was the homeroom teacher. I really didn't like her and am glad that she went to jail for it. although she was able to delay it because of her boyfriend and school. yeah, her bf was a student lee woo jin. and i am also very happy that the namely antagonist he ra was one with morals and also the fact that woo jin in reality loved he ra. also, I am happy that upto the end for me the male lead was ri an only because he truly love jae i. I am so happy because of that... in fact I hope that if there would be a next season then it should show the complete love story of yu he ra and woo jin and also about jae i and ri an.
