Start off as one of my fav drama but after ep 12 the story felt dragging and many points were missing from the drama like the story of the taxi driver , the grandmother, how the watch helped Sol to travel back in the past and why did she get another chance to save Sun jae and I felt that there wasn't any personality of Sun Jae other than being a loser for Sol..I wish that it was a drama where Sun Jae actually committed suicide without the taxi driver plot and in the end Sol had to become disable as it is an inevitable fate like they did in Twinkling watermelon and Sol and Sunjae would help each other to overcome their depression...I thought that the drama will be like this but then I was like no it's again that same serial killer plot...my fav character is Tae Sung ...he had the most significant role in the drama because without him Sunjae and Sol wouldn't have a happy ending
