Creating a Plot for a Shoujo Manga Artist - S0.E6

Seo loosens Wakamatsu's, Nozaki's, and Mikorin's trunks, and they float away. Kashima finds them and gives them to Sakura. When Sakura comes to return them, she throws them not far enough, and a wave washes them away. Using that experience, Nozaki comes up with his manga scenario.
