Natsuko, who divorced her husband 10 years ago, raised Tatsuaki with just one woman. He worked desperately not to make Tatsuaki feel pity, and when he noticed, Tatsuaki was at the age of graduating from college. With this, I felt a sense of emptiness as if I had a hole in my heart when I was relieved to raise my child. When I was feeling lonely, Tatsuaki invited me to a hot spring. Occasionally, Natsuko went to the hot spring with Tatsuaki to relax in the hot spring.
