Sho is a loner who works at a small factory. He has no friends, hardly associates with his work-mates and is regarded as a weirdo because of his love for gun models. One day he buys a real gun from a local yakuza. This boosts his self-confidence and he overcomes his insecurities and presents a bouquet of flowers to Eiko, who lives in a classy apartment and with whom he had fallen in love. (Source: theMoviedb)
