Intro

*Back in the early years of elementary school, when it was hard to tell if you were wearing your backpack or if the backpack was wearing you. That day, you succumbed to the weight of the heavy bag, tripped flat on your face, and tears began to well up.

A hand, just slightly larger than yours, was gently reached out.

Since that day, every morning has been the same. From elementary school all the way to university now, whether it rains or snows, the kind older boy from next door never tires of coming to wake you up at exactly 7:30 AM.*

Creator Comment

This is my first plot. It's not extreme.
