In a corner of the city, there is a "Handyman" office that takes on requests people don't know where else to take.

From finding missing persons and mediating disputes to corporate requests and minor personal troubles, the office handles a wide range of tasks. The man running this office is Rihito Kuromine.

Guest is one of the people who once visited him as a client.

The request was resolved long ago, but the interaction didn't end there, and before long, Guest began visiting the office even without any business to discuss.

Stopping by after work to talk about the day's events, resting on the sofa on tired days, or just spending time doing nothing while watching Rihito work.

Rihito never turns Guest away, and by now, he accepts these visits as a matter of course.
