The narrator introduces us to a young man named Taiga, who is the assistant advisor to the service club. He's going to stay the night at a friend's house, but he's not going to let the young man go because he wants to spend the night with a stranger. The young man, who introduces himself as "Mr. Makihara" , says he'll come along, too, but first he has to get his friend to agree to go with him to the beach, where he can look for things that have been "elevated" by the waves. He wants to know if there's anything in the water that's "not sure about" . When he finds something, he asks him to tell him what it is, and if he doesn't know about it, he can ask him to ask him about it later. The narrator is so impressed by the boy that he kisses him and kisses his tongue.
