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.

Motoharu asks Nanami out on a date but she blows him of to secretly buy him a present, but it isn't much of a secret because he follows her. The next day Motoharu is kind of mad at her but they are able to reconcile after exchanging gifts. Things are looking good between them until Motoharu has another run in with Yuri.

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.

The relationship between Nanami and Motoharu has ended and a week has passed without even as much as a word between them. Takeuchi just can't sit back at let things continue as they are, so he invites Nanami over to cheer her up. Motoharu is beginning to regret what happened between him and Nanami.

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 is finally able to accept Motoharu and they get back together and as if nothing happened they return to their normal school lives. But things are still not settled between Motoharu and Takeuchi because there's a sort of rivalry going on between them and Nanami is at the centre of it.

Motoharu tells Takeuchi that his Mom is getting a divorce and will be moving to Tokyo and while they're out Takeuchi feels the need to tell Motoharu that he confessed his feelings to Nanami. Nanami remains unsure of what to do about her deteriorating relationship with Motoharu, because of all that has happened with Takeuchi and Yuri.
