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.

Uzaki visits the café where Sakurai works, much to his dismay. An encounter with a cat goes horribly awry. Sakurai eats lunch with an actual friend.

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.

Uzaki tries to get Sakurai out of the house over the extended Golden Week holiday. A crowded train takes Sakurai someplace he doesn’t want to go.

Uzaki starts her part-time job. Sakaki orchestrates a summer getaway for the four friends, including a fun day at the beach and a spooky night walk.

Sakurai asks Uzaki to join him cuddling friendly felines at a cat café. Uzaki asks Sakurai to accompany her to a pub for drinks on her 20th birthday.

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.

Sakurai meets Uzaki’s mother, who’s surprised to learn some basic facts about him. A sudden change in personality leaves Uzaki’s coworkers befuddled.

An innocent trip to Tottori soon becomes a calculated effort to turn Sakurai and Uzaki into a full-fledged couple. After all, Tottori is for lovers!

Sakurai makes Uzaki clean up her stuff, then takes cooking lessons from her mom. A solo karaoke trip spirals out of control and ends in disaster.

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.
