Hinako es una chica que llega a Tokio procedente del pueblo para estudiar. El problema es que a Hinako le cuesta horrores hablar con la gente que no conoce, así que vivir en Tokio le costará bastante.

Hinako se entera de que el grupo de teatro de la escuela está en pausa indefinidamente. Pero motivada por las chicas de su nuevo hogar, contempla la posibilidad de crear un nuevo grupo de teatro.

Empiezan las clases y Hinako ya está sufriendo por su timidez. Las admiradoras de Chiaki comenzaron una sociedad de teatro y todas quieren unirse, incluida Hinako. Una compañera del salón y admiradora de Chiaki amenaza a Hinako, pero esta solo puede estarle agradecida.

It's been about a month since the start of the school year, and the theater society is practicing as always when Hinako notices child in the room. Kuina comments that the child has been showing up for a few days. None of the other members seem to mind that there's a child among them; in fact, they all seem to be practicing harder than usual. Since the child is next to Chiaki, Hinako and Kuina wonder if she's a theater troupe relation, or perhaps even Chiaki's daughter. Finally, Yua can't stand to listen anymore and straightens them out.

Ruriko, the theater club advisor who's just returned from a theater trip in Europe, tells the club members that the script she wrote to demonstrate everything she learned in her travels will be the play they perform at the upcoming culture festival. She's chosen Hinako to play the heroine, but Hinako messes up everything she tries to do. Yua, who feels she's lost the leading role to a complete theater newbie, expresses her displeasure in no uncertain terms, but as she watches Hinako trying her hardest, she finds her opinions changing.

Hinako's intense training under the exasperated Yua comes to an end, and the theater society is busy with wardrobe fittings for the culture festival that starts the next day. Mayuki helps with the costume fitting, and Hinako, Yua, Kuina, and all the other members begin to look more and more glamorous. While in their costumes, they end up doing an impromptu dress rehearsal, and Hinako is thrilled when she makes it through without messing up any lines for the first time. Yua reminds her that the actual performance is yet to come, and soon enough, the day of the culture festival arrives.

It's midsummer, and as the sun's rays grow stronger, the days grow so hot that they seem to burn the girls' skin. Hinako starts to worry when she sees Kuina plastered to her desk in deference to the heat. When Kuina asks why it's so hot, Hinako's answer is a profoundly simple "Because it's summer." Kuina has to accept that answer... but then she rises from her seat as if some great idea has struck her. She says that hot summer days like these make her want to visit the ocean, and suggests that all the Hitotose girls and Yua-chan make a trip to the ocean together.

Hinako's first summer break as a high school student has begun. She's helping out at the used bookstore for that very reason, but when a customer comes in, her nervousness peaks and she freezes up like a scarecrow. When Chiaki and Mayuki return from an outing, Hinako takes a break to have tea with them, and then Yua pops in to lend Hinako some DVDs with her favorite small troupe performances as well as acting lessons. Hinako can't help but smile at Yua's kindness. The next day, as she's helping out at the coffee shop, Hinako collapses while serving a customer...

One day, Hinako returns from school to find a letter from her mother. In it, her mother says she'd be visiting Tokyo to see Hinako acting. But Hinako is worried that she'll get nervous and freeze up like a scarecrow if she knows her mother is watching, not to mention she hasn't appeared on a stage since the culture festival. She even gets embarrassed just being seen working at the Hitotose coffee shop. Then she finds out about a stamp rally event planned in the shopping district, and she suggests having their troupe perform at Hitotose for it.

Kuina has completed the script for the Hitotose Troupe's first performance and is handing out copies to the other members. Chiaki's reaction after reading through it is positive, and everyone is happy to have all the details of the story in place. Mayuki is especially happy to finally have a chance to plan out everyone's costumes, and she immediately buys costumes for all the members to try. But then she learns that the "dress parade" normally happens after rehearsals have progressed to a certain point. Chiaki explains why it's too early to think about costumes, but Mayuki insists that they try them on...

One day in winter, as Christmas approaches, Mayuki wonders if the Hitotose girls can't put on some kind of event to draw customers to the coffee shop. Chiaki suggests that the troupe put on another play on Christmas Eve, and the girls quickly grow excited for their second public performance. Many ideas are shared, but they decide that since it'll be taking place on Christmas Eve, their play should be a Christmas story... and with that, the preparations begin.

Hinako is too cold to fall asleep, so she heads downstairs for a warm drink and notices a tasty smell coming from the coffee shop. Curiously, she peeks into the dark kitchen... and sees Mayuki stirring something in a large pot, chanting Chiaki's name like some sort of spell. Hinako timidly speaks up, and Mayuki's reaction makes it appear that she's hiding something. Unable to bring herself to question this strange behavior further, Hinako tells Kuina about what she saw.
