After fighting with her older brother, Amu runs away and shows up at the house of her brother's friend. She forces her way in and starts cleaning without being asked, offering her services in exchange for a place to stay. With her butt fully exposed and her massive breasts swaying with every movement, she cleans the room. Noticing that he has become aroused, she reaches down and touches his crotch. Realizing his reaction, she softly whispers, "It seems like you'd prefer this kind of service instead."
