Nanami Takahashi is a high school student entering her first year. Immediately on her first day however, she becomes the victim of a practical joke by the school’s most popular guy,
Motoharu Yano, who coincidentally also ends up in her class. While the two get off to a rocky start, they soon find themselves falling in love with one another and begin dating. But their relationship is marred by Yano’s past which includes the death of Yano’s previous girlfriend,
Nana Yamamoto, and the betrayal surrounding her death. To make matters more complicated her younger sister, Yuri, is in the same class as Yano and Nanami. As Yano struggles to come to grips with Nana’s death and his unresolved feelings for her, so too must Nanami learn to understand Yano if the two hope to continue their relationship with one another.
Nanami Takahashi welcomes the start of her high school life with great expectations of making as many friends as possible. There is much talk among the girls about a popular boy, Motoharu Yano, who has 2/3 of the girls in his middle school liking him. When Nanami asks Yuri Yamamoto, the girl sitting next to her, about Yano, the latter curtly replies that she dislikes him. Nanami is clueless of who Yano is until the day of the class nomination when she made a fool of herself by calling the name of her new friend wrongly. It turns out that she has actually met Yano along the corridors (unaware of his true identity) and he tricked her by providing a random name, resulting in the embarrassing incident in class. Nanami was initially mad at Yano but after a few encounters with him, she begins to find herself liking him.
Yano Motoharu is the most popular guy in class, the school’s basketball ace, and highly charismatic to boot! No wonder Nanami Takahashi can’t resist falling in love with him. When Yano returns Nana’s feelings, things seem too good to be true and the two begin a relationship; but Yano has a contradictory personality which confuses Nana most of the time. On top of that, tragic events in Yano’s past won’t stop haunting their relationship. Unable to halt their passionate feelings, are Yano and Nana heading for disaster or can they save each other from irreparable hurt?
