Every day, Naoto Hachiouji encounters Hayase Nagatoro, a first-year student he meets in the library while working on his manga. After reading his story and noticing his awkward behavior, she decides to tease him constantly, even addressing him as "Senpai" instead of using his real name. At first, Naoto finds her actions annoying and embarrassing, but as they spend more time together, a unique bond forms between them. Life with Nagatoro becomes enjoyable for Naoto, although he knows that his days will never be without her playful antics.
