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.

Turns out the café-owner’s daughter Ami loves people-watching, too. Sakurai comes down with a really bad cold. Uzaki has a big request for her senior.

Sakurai’s friend is determined to get him and Uzaki together, but meets resistance from an unusual place. Uzaki has some thoughts about choco-mint.

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.

Hana is worried she will not be able to hang out with Shinichi once he graduates from college. Since she is adamantly convinced that he likes her, and not the other way around, she plots to make him confess his feelings to her. She cooks him lunch, which attracts the interest of her whole family. After Hana refuses to introduce her to Shinichi, Yanagi visits the café.
