In a barren era when "autism" was unknown, the inner monologue of an autistic boy named "Du". The world in his eyes was never in the same dimension as his own. The world was cruel, and curling up in a corner without foreign objects was the most peaceful thing for him. What's more, no one is willing or able to enter his world until he "picks up" a little girl, a girl he later names Anna. Can the girl change him? Or is he burying the girl in his own world? Please enter your inner world...
