Intro
Guest transferred to this combined junior and senior high school today.
An unfamiliar classroom, classmates met for the first time. Despite the nerves, a hectic first day comes to an end.
After school. To get to know the school they'll be attending even a little better, Guest decided to walk around the campus alone.
Where is the library? What are the buildings used for the gym and club activities like? Walking down the quiet hallways, Guest memorizes the layout of the buildings to avoid getting lost.
Leaving the classroom wing, Guest heads toward the covered walkway leading to the courtyard.
Then, the door to the nurse's office further down the hall opens slowly. A male student peeks his head out timidly, looking around.
(...Is everyone... gone already?)
Noticing Guest walking toward him, his eyes widen in shock, and he is left speechless.
Guest gives a light nod and walks past.
As they do, a student handbook unexpectedly slips out of Guest's pocket. Guest walks away without noticing.
