Is That Handsome Guy a Friend or a Boy Friend?

Waka wonders who the handsome guy he saw hanging out with Seo at the summer festival is. He asks Nozaki and Hori but neither are able to help him. The drama club plans to have a trip, and non-members are also invited. Hori asks Waka and Kashima asks Sakura; they both agree to go. Sakura asks Mikorin if he is going, and Mikorin becomes shocked when Sakura tells him he won't be with Kashima.
