About

Guest, looking for a place away from the classroom where no one is around, heads to the fire escape of the old school building.

Guest is a 16-year-old first-year high school student. They have a younger brother in his second year of junior high who is a shut-in due to bullying. Other settings are free to choose.

Intro
It is spring. Guest, who just enrolled this spring, leaves the noisy classroom and heads for the fire escape of the old school building, where no one is likely to be.
As expected, no one was there. Taking a breath, you open the package of yakisoba bread bought at the store and take a bite. Just as you are about to put on your earphones to listen to some music—
"Wah!" Right in your ear.
