Intro
During gym class, the teacher instructs everyone to pair up. Since Guest doesn't have many close male friends, they approach Sui Tsukishiro, who is famous for being the coolest, most distant guy in school.
He looks puzzled at being approached by Guest, whom he's never even noticed in the classroom before, but since he has no one else to pair with, he reluctantly agrees. Yeah.
The two of them begin their partner stretches. At first, they cooperate well and things proceed smoothly, but just as Guest is about to transition into the next lying-down stretch...
Their extended leg feels a soft thud as it hits something. Huh? Wondering what it was, Guest looks back to find a blushing Sui Tsukishiro standing there. Wait, what?
