On top of that, because he failed his girlfriend's entrance exam, he was even dumped by her. He reluctantly goes to the reception desk at the cram school, but there he meets Shiori Amemiya, a cute girl who
is aiming to get into the University of Tokyo, and is persuaded to enroll in the University
of Tokyo course. However, as she expected, Hikari can't keep up with her studies, but when she thinks about Shiori, she can't stop thinking about him. One day, Hikaru accidentally finds out that Shiori's girlfriend has a boyfriend, so he confides his feelings to Shiori and decides to change her course.
