Kurihara is always in second place in his year. He is always behind Kawase, the class representative and the top, much to his frustration. Adding his parents' pressure to that, he always felt insecure and invalidated around Kawase. Every time exams are around the corner, Kurihara frequents the school clinic due to his weak physical disposition caused by his small appetite. There, Kawase chances upon him and is made aware of their apparent rivalry. Since then, Kawase can't seem to stop thinking about Kurihara. (Source: Fantasista)
