Reiko eventually moves to Tokyo for professional research work, leaving Ryuuki alone. Ryuuki generally shows very little interest in girls or romance. However, everything changes during one summer day when his friends introduce him to an adult video featuring a popular new adult actress named Kiriru (also referred to as Kirill-sama).
The show's nostalgic value is heightened by its meticulous attention to detail, from the character designs to the animation, which perfectly captures the carefree essence of childhood summers. This deliberate creative choice serves as a testament to the enduring power of nostalgia, which can evoke both joy and melancholy in equal measure.
The chapters were originally serialized between 2022 and 2023 in the adult manga publication Comic MILF .
