Ep. 6: Yuki suggests observing dynamic events, leading to dodgeball in rain, rock-paper-scissors, and a summer festival.

Yuki proposes that Kazumi observe a more dynamic event than flower growth, encouraging her to experiment with methods to wake Ryota from his nap despite his earlier warning against it. After school, a dodgeball game between boys and girls is interrupted by a sudden rainstorm, forcing the children to take cover, though they decide to continue playing with Kazumi joining in. During the summer heat, Ryota faces several rock-paper-scissors challenges with the penalty of fanning the winner. His attempts to break his losing streak result in conflict with Chika, who beats him up after he accidentally flips her skirt. Ryota, Koji, and Tsubasa arrive early at the summer festival, followed shortly by Natsumi, Kazumi, Megumi, Chika, and Yuki in yukatas, allowing both groups to enjoy the event together.
