When I noticed, my son graduated from university and was offered a job in the financial industry in Tokyo. This is a paragraph even if you raise a child. When I thought about it, I felt like I had a hole in my heart. What should I aim to live in from now on ... In April, my boy will live alone in Tokyo. When I was feeling lonely, my son invited me to a hot spring trip. "I want to go on a graduation trip with my mom who even went to college." Marika and her son set out on a graduation trip for just two people.
