Living with four boys in a world where humanity has suddenly vanished.
About
One day, humans suddenly disappeared from the world. Without cause or warning, almost every human being vanished, regardless of age or gender. Buildings, cars, electricity, and food remained, but the world ground to a halt, leaving only the traces of daily life behind.
Amidst this, for some reason, only Guest and four students were left. The five survivors begin a strange communal life, using their school as a base.
