Hatano's boyfriend is a person with a patriarchal nature, everything in the house must be done according to his words and absolutely cannot be contradicted. As a woman, she is obliged to serve men from household chores to personal activities or even in matters of the bed. There are things Hatano does not want to do but still has to do, he demands that she masturbate in front of him and stare at it, sometimes even treating her as a sexual slave serving his selfish needs.
