Can't say that I liked this movie. The story was okay, but it was boring. The romance wasn't so much of a romance really, as the guy was well aware of their age gap and he didn't want to fall for a minor. Also, it was obvious that the girl didn't love him because of who he was, rather, she was attracted to him because she had lost the most important thing in her life: running. So, like I said, the theme was interesting. The presentation of the theme wasn't. Nana is a so so actress for me. She doesn't show a variety of emotions and I find her tiring to watch after a while, as she is passive. But I can't say that her acting is terrible. But she was one of the reasons why this movie was not entertaining. The rest of the performances were really good, especially from the male lead. The ending was nice too.
