Nanako, who lives an ordinary life with her husband, one day calls for a repairman when her water pipe breaks. The worker who comes is a seemingly unremarkable young man named Mitsuru Kawase. Mitsuru has come to Tokyo to train and take over his family's construction business. He starts the repair right away, but water sprays out from the pipe. Though he's diligent, Mitsuru seems a bit clumsy. A few days later, Nanako encounters Mitsuru in a changed state after being fired from his company. She wants to stay by his side for just one night… and so she takes up her pen to write a false letter to her husband…
