Mamoru Kitaoji is known as the prince of the sales department because he never turns down a request: changing lightbulbs, hauling boxes, taking over impossible clients from retiring colleagues. His cheerful helpfulness is a mask worn so long that he does not know how to take it off, and his colleagues freely exploit it. His opposite in the office is Maoko Kurone, a quiet woman from the General Affairs department who absorbs her boss’s senseless mood swings with a blank, stoic expression and keeps to herself.

One evening after a particularly draining day, Mamoru walks home alone sipping a beer while his coworkers go out drinking without him. In a neighborhood park, he stumbles upon a sight that shatters his image of Kurone: the usually glum woman is utterly delighted, laughing and playing with a group of stray cats. This secret bond over the cats becomes the foundation of an unlikely after-hours connection.

The park is home to several community cats, and Kurone cares for them through the TNR method: trap, neuter, return. Mamoru begins joining her, and the park becomes a safe space where both can drop their work personas. For Kurone, it is a refuge from a social environment that feels threatening; for Mamoru, it is a place where he does not have to perform or please anyone. Through their shared encounters, Mamoru starts to question whether his life consists of anything beyond meeting others’ expectations, and Kurone slowly learns to trust another person.

The story follows their gradual relationship as they navigate workplace pressures, misunderstandings, and the simple pleasures of feeding cats. The narrative also grounds itself in the realities of community cat care, treating the animals not just as cute mascots but as creatures that require responsible attention. Over the course of the series, Mamoru and Kurone discover that the park is not only a safe space for the cats but also for themselves. The manga concludes with the two having found a quiet, meaningful connection that helps them each strike a better balance between their work lives and their true selves.
