Mio divorced her husband before her children could remember, and worked hard to forget her grief. I came to a hot spring inn on a vacation I took for the first time in a long time. He is served by a young man who works at an inn he visits. At first, he chatted that he was a cheerful young man, but the pendant that the young man was wearing was the same as the one that Mio gave him when they parted. The young man is convinced that he is his son. Mio hears from the young man that his father ran away at night, leaving behind a debt, and that the son of the guarantor works at the inn from morning to night.
