Nanami Takahashi is entering her first year of high school with great hopes of making many new friends. She learns about Yano Motoharu, a popular kid in their class, after meeting the bashful Yuri Yamamoto. Yuri dislikes Yano due of his previous connection with her older sister Nana, and Nanami initially dislikes his attitude as well. Nanami, on the other hand, quickly warms up to Yano and develops feelings for him. After spending more time together, the two decide to start dating. But their love is not without difficulties; Yano has difficulty opening up to Nanami because his previous lover, Nana, died in a car accident the year before, and she had been dating one of her coworkers at the time.
