The Story of How Being Kind to the Neighbor Girl Whose Yelling Could Be Heard Every Night Made Her Grow Attached

A lonely office worker hears shouting from next door every night. His only warm connection is bandaged neighbor girl Yua, who greets him as uncle. After her mother brings a boyfriend home and locks her out, Yua stays at his apartment, eats dinner, then strips and offers sex as repayment, explaining her mother takes money from men and has her thank them with her body; flashbacks show her being forcibly held down and assaulted. The man refuses, but Yua insists, performs oral sex, and they have vaginal intercourse while she endures pain to keep his kindness; after he ejaculates inside and on her, she clings to him and asks to keep getting along. In the morning Yua's mother finds her at the neighbor uncle's door and casually asks if he enjoyed playing with her daughter the night before; distressed Yua insists her mother is not like that, then leaves for school. The mother proposes monthly payment so he can freely use Yua under parental authorization instead of reporting him; he agrees while secretly resolving to kill the mother once Yua can survive alone, and the final panels show an older Yua in a sailor uniform.
