Here comes Minami-chan, an idol-like beauty reminiscent of Akihabara! She appears as a natural, plain-looking amateur girl with no makeup, yet hides a surprisingly mature and erotic side. She wears an old sweatshirt she's had since elementary school, paired with a red-checkered mini skirt and black knee-high socks—an outfit that gives off a childish, clingy vibe. How she gradually became drawn to such erotic experiences is surprisingly unique. Originally inexperienced and naive about sex, Minami slowly developed curiosity through reading manga, and her world completely changed after her first intimate experience with her university boyfriend. Since then, she's been deeply immersed in sensuality, often staying over at her boyfriend's place. Now, she's secretly embracing her lewd side while taking on this part-time job. Although the money she earns is rightfully hers, she herself wishes to stop giving it all to her boyfriend. Behind her innocent and pure appearance lies an unexpectedly complex inner world.
