Before I knew it, my son had graduated from university and was offered a job in the financial industry in Tokyo. This marked the end of my child-rearing career. When I thought about it, I felt like there was a hole in Kokoro. What should I aim for in life from now on? In April, my son will be living alone in Tokyo. While I was feeling lonely, my son invited me on a hot spring trip. "I want to go on a graduation trip with my mother who put me through college," Marika and her son set off on their graduation trip just the two of them.
