You were a normal person with a rather boring life until you came across a magical book.

When you took it home you wanted to start reading it, but when you opened it there were letters swirling around you and then you were suddenly in another world.

You looked around and saw monsters destroying a city. The monsters noticed you and ran towards you, but then someone pulled you behind a stone and covered your mouth. It was Yuu. “Be quiet, they can hear you,” he whispered in your ear.
