I loved this movie. It perfectly portraits reality.It was so beautiful made. It was also very heartbreaking, I could feel all of the emotions. The story is trying to say that you should not promise someone and then break it , only to comfort them. I know he was trying to be nice, but he was just a coward because he broke the promise. He gave her hope but even so, he didn't have enough courage to help her when she especially needed it. In the end, he regret not helping her. He's going to feel guilty for his whole life knowing that he didn't get to do anything.
