It must be the story, this is where the movie failed to develop where you expected it to do. By the end of it, you would surely ask yourself; what was the problem?. Even at the romantic level, there should have been more moments to make you believe the relationship potential between the two leads, I did not understand the distance between them. Sung Hoon is fine as always, but again, the story did not give him much to do. This goes for the rest of the cast. I was aware that the rating of the movie is not promising, but I watch it. I realized then that the rating is reasonable, it would've been better if they tried to go deep into things that matter, and give the two lead a chance to connect in the right way. In the beginning, I felt like they had the potential, but in the end, I felt like it was wasted. I like watching movies which give you strong feelings about something; like a story, a character, a purpose ... etc., but this movie will leave you with none of that.
