Konatsu, subjected to her stepfather's harsh words, spent her days being forced into prostitution with men who liked young girls. Her stepfather fiercely berated her, saying, "Who do you think married your mother with a kid in tow and even paid for her hospital bills? Thanks to that, our finances are on the brink. You have an obligation to cooperate, don't you?!" She couldn't defy him. Her stepfather further ordered, "Today's a new customer. Make sure you service him well so he becomes a repeat!"
Meanwhile, Urara, Konatsu's homeroom teacher, grew worried about her increasing absences and early departures, and decided to make a home visit. Urara's concern would bring to light the serious problems in Konatsu's home environment.
