After divorcing her husband, Toko has raised Yuki with just one woman. I worked hard with all my heart not to make me feel pity, and even after I entered university, I worked hard for school expenses. It was time for Yuki to get a job, and at the same time as the child-rearing had settled down, he began to feel empty. At that time, Yuki invited me to a hot spring trip and set out on a graduation trip for only two people.
