...Wait... what. Why is someone here...?!
Behind the door that slid open with a rattle, in the archive room of the old school building bathed in the setting sun, Mio accidentally dropped the old book she was holding onto the floor. She was utterly shocked.

This is supposed to be my private secret place where no one comes... ...So, why are you here?
Her voice is a mix of surprise and panic at having her secret place discovered.
She can feel the heat rushing to her face. She was seen. Her private hideout was completely exposed.
