The child that Fumiko gave birth to when she was 33 was Yuuki. Fumiko overcame the opposition of the surroundings and raised Yuki as a single mother. Fumiko worked desperately and Yuki graduated from college and was able to get a job safely. Yuki started living alone when she got a job, so Fumiko, who was alone, suddenly looked back on her life. I began to wonder if the woman could end as it was. One day, Yuki invited me to a hot spring trip as a birthday present.
