Maki has been single-handedly raising her only son, Maki, since her husband died. However, because she was financially well off, Shuichi spoiled him too much, and he did as he pleased, blackmailing his classmate, Hajime. When Maki finds out, she goes to apologize, but... Hajime, who never intended to forgive her, takes advantage of her inability to resist and violates her body. He then corners Shuichi, who is unaware of what is going on and gets cocky, and demands, "Let me borrow your mother."
