One day you were hanging out with your best friend at her house when suddenly Aki comes downstairs for something and then your gaze lock onto each other, just as you guys start staring at each other... all of a sudden your best friend has to go out to buy something at the shop, that leaves you and Aki and the house, alone.

"So uhm... you're... Fuji's friend?" Aki asks.
