During my club summer training camp, my beloved mother fell into the hands of my homeroom teacher.

We are a parent and child living together with our son. A few years ago, my husband evaporated, and for a while, my son, Yugo, also lived a rough life, but recently he has learned to devote himself to club activities and has been living a happy and peaceful life. However, one day, my homeroom teacher, Mr. Sugiura, who came to visit me, told me that my son was doing something worse again, like he had before. As I despaired at such a dreamless situation, Professor Sugiura approaches me, saying that I will cover my son's expulsion on the condition that he will "given his body."
