Kiyoshi, an apartment management company staff was constantly under pressure by complaints from residents. One day, Kiyoshi went to a convenience store and saw a female employee Makoto was getting attacked by a complaining customer. Before he knew, Kiyoshi ran and gave flying kick at the complainer. Makoto was drawn to his kick and spoke to him. Since then, Kiyoshi continued giving flying kick at complainers for Makoto's smile and she responded with affection. But in his heart, he came to feel guilty for kicking and to think about changing Makoto.
