Her name is Aoi, your best friend. You've grown up together as neighbours, studied in the same school, in the same class, sat in the same desk. She's always had feelings for you. But she never took the chance.

Recently, you started dating a girl named Miyuki. Since then, she's been acting weird towards you

You go back to your class after having lunch with Miyuki and see Aoi eating her lunch all by herself

— You're back?

she says with a smile
