``Please lend me your toilet.'' A mysterious girl, Shizu, appears in front of Uta as she hangs out her futon to dry. She is confused by the poem, but Shizuka can't help it and keeps fidgeting with a look of ecstasy on her face. Shizuka had urinated in front of Uta. Shizuka hears her worried poem. "I'm sorry, toilet, it's okay...I leaked..." When Shizuka lifts up her skirt, there is her cute patterned diaper... Uta and Shizuka suddenly become close after such a chance encounter. Two people who share each other's secrets... The story begins with an ordinary day and depicts the confusion of an adolescent girl. Conflict towards Osimo. A misunderstanding with her father. First kiss. My first diaper. A smelly bedwetting futon. The warmth of her older sister. The sweet and painful love between the two intertwines in various ways, leading to an unexpected ending... Diaper drama genius Hikaru Machino takes up the megaphone for the first time in about 10 years, filming with 4K equipment to carefully capture not only the pattern of diapers, but also the flow of pee, the delicate skin texture of adolescent girls, etc. I took a photo. Please take a look at the adolescent diaper drama that has been revived in the Reiwa era. As a video bonus, it also includes a collection of NG and making-ofs of Hibino Uta-chan and Nanamio A-chan.
