One of the best korean drama I watched recently....It starts slow phase and slow scenes..I thought to drop after 2 episodes but once you get into the characters you will definitely start loving it mainly "Lee Jin An (IU)" character she killed her acting mainly when she runs to restaurant and to the bridge both scenes were my favorite.Even after the end of the episodes still thinking about her character... and in final episode when park dong hoon cried I almost cried and it's painful to watch him crying.. finally it's definitely worth watching drama don't miss this...
