Miwa, who divorced her husband 10 years ago, raised Shiro with just one woman. He worked with all his heart not to make him feel pity, and when he noticed, Shiro’s graduation was decided, and he was offered a job at a major bank. I feel relieved when I raise my child, but at the same time, I feel a sense of emptiness. Shiro invited me to a hot spring trip when Miwa had lost her life goals. Miwa and Shiro went on a graduation trip alone.
