A boy's dream is to marry his elementary school teacher. He gives her a ring and tells his love, but she has a fiancé. The boy meets the rival, and decides to fight a duel.
No one thinks the young student can marry his teacher, even if he has a crush on her seriously. So, at first, I think the story is funny and fantastic. I like the scene that he writes down his wish for marriage as a plan in 2015. He looks very pure and cute for me. Generally speaking, a child gets more serious when he is treated as a child or ignored by grown-ups. The boy in the film is not an exception, and he acts in an excessive way. I have to admit that the story is serious, not only fantastic.
The message in the film is "Don't make light of children."
