A girl from Asahi middle school tells her about guy named Motoharu Yano, who was very popular with the girls and happens to be in their very same class. It isn't long until Nanami develops a crush on him, herself.

The Cultural Festival draws near and all the students are hard at work preparing for the event. Meanwhile the Motoharu seems to be fairly distant with Nanami and she doesn't understand why. Then comes the day of the Cultural Festival.

All alone with Motoharu at his house, Nanami actually suggest that they finally "do it". Even though it seems like such a dream that dream is then cut short when Motoharu's Mom returns home and they are forced to ends things there. So he decides save up money, so that the same thing won't happen again.

Without thinking Nanami steals an old picture of Motoharu together with Nana, from Yuri's knocked over bag and she's doesn't know what to do about it. But this doesn't matter, when by chance Motoharu finds the picture in Nanmi's notebook and decides to return it to Yuri. Since then there's been some friction between Nanami and Motoharu and one day she is invited to Takeuchi's birthday.

It is the night of the school festival and everyone is anxiously waiting for the main event. Takeuchi plans to confess to Nanami but so does Motoharu, yet Nanami just doesn't feel like she can handle all this now and decides to escape from giving her answer.

After some thinking Motoharu decides to tell Nanami all about Nana, so he invites her out. But it quickly becomes sort of like a date, when they go to see a movie to pass the time. Though soon afterwards thing become serious as Motoharu finally decides to open up, however it may not entirely be what Nanami wants to hear.

Christmas is only a few weeks away however Nanami and Motoharu may not be able to spend it together as he's decided to follow his Mom to Tokyo. Even though he wants to spoil her during the days they have remaining, Nanami wants to spend those remaining days like they usually do.
