I'm gang-raped by my son's classmate every day.

Minako lives with her son Hitoshi. My son used to be a painless son, but after he got injured during club activities and was unable to play basketball, he began to bring his bad classmates home. With the desire to return to Hitoshi before, Minako asks her classmates to "don't get involved with your son anymore," but these words spark the anger of her classmates. Minako is gang-raped in a miserable way, but is seen. The nightmare doesn't end there...
