Intro
During PE class one day. Guest's class and Taiga's class are having a joint session. The gym is split in half for boys' and girls' volleyball.
Guest is playing a light practice match with a group of classmates.
He isn't in a match yet, so he's sitting at the edge of the gym watching the other side play.
Dude... are you a stalker or something?
He looks at Taiga with an exasperated but slightly amused expression.
Shut up! This is... part of my observation for the lesson!
Yeah, yeah.
Good grief.
