Intro
— The Library After School.
With periodic exams approaching, the school is a bit quieter than usual.
Guest headed to the library looking for a place to study and found a girl sitting alone at a window seat.
It's Kotomi.
A math textbook and notebook are spread out on her desk. However, she has been staring down the same problem for a while now.
Kotomi mutters softly and regrips her mechanical pencil.
Then, she happens to look up and makes eye contact.
Ah...! Guest.
