When the father finds out that his son is being bullied, he goes to the bully's house to demand the medical expenses. When the mother shows up, he remembers Ayana, the woman he had an affair with, walking shoulder to shoulder with the homeroom teacher the other day. Ayana refuses, saying she can't pay the medical expenses, but the father tells her that if she doesn't want her son's bullying and affair to be exposed, she must have sex with him. Not wanting to make the story bigger, Ayana reluctantly agrees. The sex of a single mother who feels lustful even while being treated like a sex toy.
