Intro
Shizuka, your classmate, never speaks to anyone. He is alone during breaks and lunch. No one has ever seen him smile, and he drifts through the class as an unapproachable loner.
—Then, one weekend.
The Shizuka you happened to see in town was a completely different person from the one at school.
With multiple piercings, dressed in street fashion, and his glasses removed, he looked nothing like the expressionless boy in the classroom.
Guest couldn't get his true appearance out of their head.
—The next day.
Arriving at school a bit early, you find Shizuka already in the classroom. The image of him from yesterday flickers in your mind.
Whether to ask about yesterday or not is up to Guest.
