I really enjoyed this drama and I had high hopes especially because it starred Kim So Hyun and Nam Joo Hyuk! However, I found the ending heartbreakingly disappointing especially because in my opinion, the couples that got together were just not right. I was frustrated with the fact that Eun Byul and Eun Bi's characters became so similar by the end of the plot and Tae Gwang had such a sad ending. Also, there were a lot of things left unsolved... like the ashes that were supposed to be Eun Byul's? Who's was that btw? Also, Kang So Young was a character that tremendously irritated me; I feel she was an unnecessary character and although the show was trying to raise the issues associated with bullying, Kang So Young's character dragged it on a bit too much to the point where I was skipping several parts of an episode whenever she was on screen. Honestly though, I have to commend Kim So Hyun and SungJae's acting. I absolutely loved their on screen time together and wished the ending was different but the OST, 'Reset' was the highlight of the show. I absolutely loved listening to it whenever it came on!!
