When I am currently watching the movie, I can't help but think of what the ending will be. Most of us wants happy endings, but this movie really tells about the reality and what a single moment can do to change something that you treasure. Just one small mistake.. that changed their lives. An eye opener. Park Bo Young and Kim Young Kwang have really good chemistry. A message to cease every moment until you lost your chance. It really breaks my heart. It tells us a lesson that some things are really not meant to be.
