It's Nanami Takahashi's second day at her new high school and almost as soon as school starts she quickly makes some new friends in her class, like the unsociable Yuri. 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.

Following Motoharu's confession during the Cultural Festival, Nanami seems pretty out of it as she couldn't sleep at all last night. It's isn't long before her friends discover what happened between them. Once school is over and Motoharu sorted out everything in the student council meeting, they go on a date to the movies. Time passes by and winter comes and Nanami is thinking about what to give Motoharu for Christmas.

In her room, Nanami uses this opportunity to ask Motoharu about his past Yuri and it takes some time for him to give her answer. As Motoharu leaves Nanami feels reassured with what he told her but it may not be the entire truth. It turns out that Motoharu's friend Takeuchi has been hiding the truth he knows.

Nanami and Motoharu's study session in interrupted when, out of the blue, Yuri turns up on Motoharu's doorstep, with something to tell him about her sister. It's to do with the reason why Nana was in Kagawa's car 2 years ago. Soon after that Nanami and Motoharu end up having a quarrel about it.

With things going nowhere between Motoharu and Nanami, Takeuchi is unable to hold back his feelings and decides to take the initiative. Nonetheless he may have timed this wrong and Motoharu wants to stop him before it's too late. What are Nanami feelings towards the both of them?

It's a normal school day, following the school festival and Nanami decides to get back together with Motoharu but under the condition that he tells her all about his first love, Nana. The two go out on a date but Nanami brings along Takeuchi, in order to get Motoharu to spill. Instead of learning something about Nana, Motoharu ends up telling her about his late father.

Nanami's parents are going to a wedding on the weekend, so she takes this opportunity to invite Motoharu to sleepover. On the day Motoharu's pretty excited about the whole thing when all of a sudden he receives a call from an upset Yuri. So instead of meeting up with Nanami he goes to be the one at Yuri's side. Meanwhile Takeuchi is on a date but he can't seem to get Nanami of his mind.

Nanami is also worried about the impossible entrance University exams she has gotten herself into and she is begins studying like mad, in order to raise the chances of being accepted. But more importantly Motoharu still hasn't given Nanami an answer as to whether he would be moving with his Mom or staying. What will Motoharu's answer be?
