High school student Ana suffers from incontinence and accidentally defecates during class. Her compassionate female teacher, Izumi, gently tends to her. Witnessing this scene, classmate Mayoi grows jealous of Ana and begins longing to be cared for as well. Her obsession with soiling herself intensifies, and she ends up defecating in her leotard during rhythmic gymnastics practice—only to realize it was all a dream, plunging her into deep despair. A drama centered on in-clothing excretion, this work explores adult emotions and bodily struggles through its unique theme.
