My family consists of me, my wife, and our son, who is preparing for entrance exams. Recently, my son has not been feeling well, so one night my wife came to me for advice. Apparently, a friend of ours named Ryuichi, who is in the same class as our son, has been coming into our son's room almost every day recently. Our son has always been shy, but Ryuichi is big and has a rough demeanor, so she wonders if he is bullying him.
