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.

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.

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.
