Autumn's Potato Moon (S01E06)

The students at Ryokushou are gearing up for the Miyama school district's sports festival. Itsuka is feeling bashful around Nagomu, which leads her to act somewhat curt with him. However, his enthusiastic cheers fill her with a sense of familial warmth. Unfortunately, Nagomu's father, Heigo, gets a bit too enthusiastic and ends up injuring himself. This forces Nagomu and Itsuka to fill in for him and take part in the parent-child event. Meanwhile, back at Ryokushou, a woman claiming to be Itsuka's mother makes an unexpected appearance.
