As for me, this is a raw but beautiful movie that teaches that ability to fall in love doesn't disappear with becoming old. So you all youngers must remember this when you meet olders and become close friends with them: they might secretly have love passion for you which they suppress inside of themselves. And the fact that they still fall in love is not bad at all, it's exciting, beautiful, but sad at some point too. Other ideas of this movie aren't shown earnestly enough for me, so I don't pay attention to them. Well, they are problem of jealousy, fairness, guilt, understanding, etc. It's amazing that the old man was played by actually a young actor. Amazing makeup and acting of the actor. I've become curious about Park Hae Il. Erotical scenes are so natural here. This made me realize how korean movies are very different from korean dramas. Compared to k-movies, k-dramas are just 'cheap' entertainment industry that washes viewrs minds with tabboed cliches. (No, here are no erotical scenes between the girl and old man, don't worry). Still I said that this movie seems raw. I don't know...Many scenes feel abrupt, incomplete or draggy and slow. The characters are not shown precisely and deeply enough: they are rather just sketches for actual very interesting characters. Also here are many beautiful scenes and views in this moive. I think people should watch this movie to develop their capability to feel different emotions and of understanding of this world.
