College junior Shinichi Sakurai just wants to be alone, but loudmouthed sophomore Hana Uzaki sees it as her mission to keep him from being lonely.

The café owner and Ami encourage Sakurai to take a downhearted Uzaki to a fireworks festival in an attempt to get things back to normal between them.

Uzaki reminisces about her time with Sakurai in high school, then cooks up a scheme to see what he's like when he's drunk as summer comes to an end.
