If you have the title "Fish out of water", you may imagine a story of fish. However, this story isn't about a fish, but a man who works in a company. He rows a boat every day and goes to his company every day. Perhaps because he commuted by car before, he is always irritated because of a traffic jam, so he calmly commutes by a boat. One day, a strange woman waits for him to row a boat in front of a wharf. He is compelled to get into a boat with her and rows. On the next day, more people wait. He is irritated to commute by boat. Then he just hits upon a good idea. He starts to commute by swimming like a fish! He enjoys commuting by swim because someone don't interrupt him.
