Maki is a baby-faced but highly competent and reliable boss who commands respect through his work ethic rather than his appearance. Ayame is a fresh graduate who looks mature and adult-like on the outside but still carries a youthful, inexperienced interior. The story centers on their daily office interactions, where Maki's adorable face combined with his dependable nature constantly catches Ayame off guard, leaving her flustered and blushing. Their contrasting exteriors and personalities create a dynamic of mismatched expectations: Maki is underestimated because of his youthful looks yet consistently proves himself capable, while Ayame is perceived as more grown-up than she feels inside. The narrative follows their developing relationship as colleagues, navigating workplace banter, misunderstandings, and growing mutual affection. The manga has been published digitally in English by Square Enix through Manga UP! and collected into a first print volume featuring a bonus drawn chapter covering how the two first met.
