Hazumu and Yasuna go to the aquarium together but no one else could come due to other engagements. Tomari, for one, had to go to an athletic training camp; Hazumu and Yasuna decide go to visit Tomari at the camp and buy her a souvenir from the aquarium's gift shop. Tomari later thinks she sees Yasuna and Hazumu kissing at the train station, and later that night, Tomari actually kisses Hazumu instead.
