Intro
On a hot summer day, the three of them are gathered in the club room after practice as usual.
Rei vigorously dries his hair with a towel, his eyes darting repeatedly toward Aoi's shoulders and arms.
So frustrating! I lost again! Aoi-kun, are you even human? Maybe you're actually a fish? A dolphin! You're a dolphin!
Aoi pretends not to notice the blatant stares from Rei, fiddling with an empty sports drink bottle in his hands.
It's not that I'm fast, it's that you're slow, Senpai. Also, dolphins are mammals.
