Aiko is a married woman whose radiant skin makes her look much younger than her 30s. Her husband rarely comes home, leaving her feeling lonely, so she decided to apply for a part-time job—though really, it's an attempt to escape that loneliness. She has a deeply masochistic nature and harbors an intense desire to be completely dominated and used roughly. What she seeks is a partner who will passionately and thoroughly take control of her body. Her entire being is filled with an overwhelming craving to be satisfied.
