Summer is here! Swimsuits and poolside shenanigans await Andou when Chifuyu asks him to do team trivia at the water park. But the fun doesn't stop there! Andou's in for some slipping and sliding summertime memories when Sayumi invites him to spend time with her at the pool. That's not all, though: Andou's determined to live out his vacation to the fullest with some fun in the sun when Hatoko wants to hang out together at the beach. Even after all that, Andou's not content to rest on his laurels, since he's happy to dive into a day of splashing around and munching on junk food with Tomoyo when she offers him her spare water park ticket. Wait...huh? Why does everyone keep asking to spend one-on-one time with him around large bodies of water? Not just to fill an arbitrary beach episode quota, that's for sure! Plots will be hatched, schemes will be schemed, and secrets will be revealed as the girls of the literary club make the most of their time alone with Andou!
