19-year-old Eri, after graduating high school, became a part-timer starting a convenience store job without any dreams for the future. Unlike her student days, her working hours grew longer and her income increased accordingly. As a result, her spending also rose. Spending money became enjoyable, and her expenses kept growing. She needed to increase her income by taking on more jobs. Her work, initially limited to the convenience store, quickly expanded within a year to include a café, a sushi restaurant, and a cabaret club, eventually surpassing a monthly income of 500,000 yen. However, her stress levels grew as well, and she ended up spending nearly all her income on living expenses—such as 3,000 yen per single daily meal. To increase her earnings further, she began reducing lower-paying jobs and became increasingly interested in the adult entertainment industry through her cabaret work. Wanting to shoot an AV, she started exploring a new path—perhaps awakening a new talent by making the most of her big tits.
