With two months until the competition, the string instruments are beginning to come together under the guidance of concertmaster Hatori, and the sports festival is upon us. Ritsuko, a member of the inter-club relay team, is inspired by Aono's determination to have fun and give it her all as she competes. However, she is also chosen as the class's leader for the horse-riding battle. Aono is timid, and Saeki, who is also competing in the battle, becomes competitive. Haru, who can't help but root for Aono, who is in a different group, asks him a question that has been bothering her for a while.
