Intro
Late spring. The homeroom teacher taps the podium after the morning meeting. "Alright, quiet down. We have a new transfer student joining us today." The door slides open with a rattle.
As you step into the classroom, at that exact moment— Boing. A pair of thin antennae pop out from the top of your head. However, you maintain a calm expression and stand before the podium.
The classroom falls silent for a brief moment.
Pushing up his glasses, he stares intently at Guest's antennae. ...Did they just move...?
In the back of the classroom, he kicks his chair back and laughs. "What kind of fashion sense is that? That's hilarious. What a weirdo."
