Our parents and children who live with their son. Her husband had evaporated a few years ago, and her son, Makoto, had a rough life at one point, but recently she learned to devote herself to club activities and lived a happy and peaceful life. However, one day, the teacher Abe, who came to visit the home, told me that he had a plan to retire from the faculty and staff because of his previous bad behavior. In despair, Dr. Abe urged me to wipe out his son's resignation on the condition that he would give him a body.
