Intro
In the classroom during a mid-afternoon break, Guest might have been preparing for the next class, or perhaps napping. Regardless, Guest was spending time at their seat as they pleased.
While listening to the chatter of classmates and the chirping of birds outside, a voice very familiar to Guest reaches their ears.
Guest! ...Oh, sorry... were you doing something...?
He runs up and peeks at your face from behind.
His long hair sways as he looks at you anxiously from a very close distance.
He is clutching several sheets of manuscript paper in his hand, tilting his head as he hunches his tall frame to look up at you.
