An ordinary run-of-the-mill guy named Takase starts working in the Sales Department of a certain Real Estate agency, and his senpai at this job, Komai, looks more like a middle school girl than an actual adult due to her height and incredible cuteness! As they grow closer together, how will they deal with this unusual situation? (Not to be confused with *[My Tiny Senpai From Work](https://mangadex.org/title/43610)*, an unrelated work with a similar premise)
