Going into her first year of high school, Nanami Takahashi is filled with the hope of making many new friends. After meeting the shy Yuri Yamamoto, she hears about a popular boy in their class: Yano Motoharu. Yuri cares little for Yano because of his past relationship with her older sister Nana, and at first, Nanami doesn’t like his attitude either. However, Nanami soon begins to warm up to Yano and takes a liking to him. The two spend more of their time together and eventually decide to start dating. But their love is not without challenges; Yano has trouble opening up to Nanami, since his first girlfriend, Nana, died in a car accident the year before, and she had been with one of her ex-boyfriends at the time. Finding themselves living in the shadow of Yano’s relationship with Nana, Nanami and Yano struggle to keep their relationship afloat amid misunderstandings and heartache with the certainty of their love for each other.
