Nakado Sumire, an office worker raised in an all-female environment, begins trying her hand at marriage hunting—but nerves get the best of her, and she spends her days failing to hold proper conversations with potential partners.
One day, she blurts out to her admired coworker and the only man she can comfortably talk to at work, Tachibana Kotaro, “Please… sleep with me, just once!”
Tachibana, who secretly has feelings for Sumire, agrees—but on one condition: “Only if you’ll be my girlfriend.” However, Sumire completely misunderstands, believing he means, “Pretend to be my girlfriend to ward off advances from other women.”
