Bokura ga ita - S01

As Nanami Takahashi starts her first year of high school, she hopes to make plenty of new friends. After she meets the shy Yuri Yamamoto, she learns about a popular boy in their class, Yano Motoharu. Yuri has little interest in Yano because of his past relationship with her older sister Nana, and at first Nanami dislikes his attitude too. But Nanami soon warms up to Yano and starts to like him. The two spend more time together and eventually decide to date. Their love is not without problems, though. Yano has trouble opening up to Nanami because his first girlfriend, Nana, died in a car accident the year before, and at the time she had been with one of her ex-boyfriends. Living in the shadow of Yano's relationship with Nana, Nanami and Yano struggle to keep their relationship going through misunderstandings and heartache, even as they remain certain of their love for each other.
