Whether she divorced her husband 10 years ago, she raised Tatsuaki with just one woman. Tatsuaki worked desperately to go to college, not to make him feel pity just because he was a single-mother family. When I noticed, Tatsuaki also got a job offer from a printing company, and even after raising a child, it was finally over. When I was relieved and felt empty as if I had lost my purpose, Tatsuaki invited me to a hot spring trip, saying, "Sometimes I want you to take a break from work and relax."
