This is one of those movies that you may expect a feel good ending but instead, you are left with a "What just happened?" It was definitely a story we have seen before; a guy meets a girl and years later they meet again but the story probably won't turn out the way you want it to. There was absolutely nothing wrong with the acting. Ha Ga In and Uhm Tae Woong as the adult Seo Yeon and Seung Min were great; Bae Suzy and Lee Je Hoon as the younger characters were also good; it really was the story. A story about what happens when there is a misunderstanding. Not going to give anything else away. You have to decide whether or not you want to watch simply for the acting.
