The protagonist Runa, who works at a direct-sales shop of a miso manufacturer, receives news that her former coworker nicknamed 'Solitaire Ojisan' (Mr. Solitaire) has died in a fire. After attending his funeral, forgotten memories and unverifiable thoughts begin to surface. A literary short story that confronts the quiet details of everyday life with the weighty theme of death, written in a Kyoto dialect–tinged voice.

Kuronoda, who used to work with me, has died. Things I had forgotten, things I could never have confirmed — they drift up, one after another, without end.

A short story set in a high school classroom during summer, alternating between the lively debates of a group of high school girls and the inner world of the female teacher watching over them. In the unofficial 'girls' gathering' organized by Takagi, topics fly fast: 'Should perpetrators of sexual violence be required to undergo vasectomy?' and 'Who deserves to be Ren Sato's girlfriend?' The teacher listens idly, sucking on Sakuma Drops candy, while memories of past male students and long-forgotten incidents surface and blur into fantasy. The cool air of the classroom and the teacher's dissolving consciousness intertwine, illuminating the gap in perception between adults and the young.

From the third-floor classroom of the north building, Class 3-3, the ochre-colored schoolyard is clearly visible.
