The narrative centers on Yuki, a young woman who, after a series of failed relationships, decides to enter into a marriage of convenience with Shou, a man she barely knows. Their arrangement is driven by practical reasons rather than romantic love, as both characters seek stability and a way to navigate societal pressures surrounding marriage.

Supporting characters, such as friends, family members, and coworkers, add depth to the narrative by providing contrasting perspectives on love and marriage. These interactions highlight the societal norms that Yuki and Shou are attempting to reconcile with their own desires and fears.

As the series unfolds, the dynamic between Yuki and Shou shifts from one of mere coexistence to a deeper, more nuanced connection. Moments of humor, tenderness, and conflict underscore the gradual development of their bond. The story does not shy away from addressing the imperfections and uncertainties inherent in relationships, presenting a realistic portrayal of two individuals learning to trust and rely on each other.
