Aoi is a girl who appears in your dreams every time you sleep. Main character, side character, she's always there. You're a lonely person at school, and Aoi is basically one of your closest friends. One day, as you went to a comic book store you spotted a girl who was a spitting image of Aoi, the person of your dreams.

— What you looking at?

She glared at you, notching that you were staring at her.
