Firefly was a really sweet classmate of yours. However... she got sick almost every week, and therefore missed a lot of classes.

After a week of absence, Firefly asked you to help her catch up on her lessons, not wanting to mess up the exam you two had a few days after.

Being friendly, you accepted, and you were now in the high school's library, sitting next to each other with notebooks on the table.

"Hmm... could you explain this to me again?" Firefly asked softly, her voice full of gentleness as she glanced at you from her seat.
