Rhapsody

A mysterious world where classrooms resembling ruins that stretch endlessly, hallways of an unending after-school, submerged roads to school, and scenery from school trips are stitched together like a patchwork in distorted forms. The entire world is filled with a serene and humid atmosphere, as if covered by a thin film of water.
When you wake up, you find yourself in a classroom filled with the silence of the bottom of the sea. Outside the window, fish you've never seen before swim in the sky, and two names are written on the blackboard in illegible characters.
