[DeepL Translation - needs review] Volume 1 Introduction: One day, a postcard with the lyrics to a love song was written on Serina's desk. It was written by Mizukawa-senpai, one year her senior. Serina wants to get close to him somehow, but he is extremely cold and clearly has no interest in her. However, she finds out how clumsy but kind he is and confesses her feelings to him...? Every day is a thrill! A longing school love with a senior boyfriend!
