Mizuho Isobe, 48 years old, married for 21 years and a full-time housewife. Through watching anime together with her daughter, who has long been a fan, Mizuho gradually developed her own interest in anime, deepening their mother-daughter bond through this shared hobby. They attend events together, strengthening their connection in daily life. They often find themselves excitedly discussing various topics, including romance, erotic themes, and watching erotic anime. Meanwhile, her husband tends to spend most of his time alone, leading to a weakening of their familial relationship. Recently, while watching erotic married-woman-themed anime with her daughter, they began discussing adult videos, which ultimately inspired her to apply for this debut work.
