This is a show about two brothers who already chose each other wrong the first time, now stuck in a detective agency that runs on pure chaos and spite. The comedy lives in the gap between what Kou wants (his brother back home) and what actually happens (his brother is a disaster who runs a detective agency in the slums). You're watching two people who love each other figure out how to live in the same room again, one weird case at a time.
Kou tracks down his estranged brother Takumi in the rundown slums, only to discover he's become head of a small detective agency. Rather than drag Takumi back home, Kou decides to stick around and help out at the office, taking on whatever work comes through the door. What starts as a temporary arrangement becomes something more complicated as the two brothers navigate their fractured relationship while handling peculiar cases and meeting the agency's rotating cast of oddball clients and associates. The show balances genuine moments of brotherly reconnection with lighthearted comedy that emerges from watching misfits collide in cramped spaces. The slum setting gives everything a gritty, lived-in feel even when the tone stays playful. Cases range from the mundane to the absurd, rarely taking themselves seriously. The real heart lies in how Kou and Takumi slowly rebuild trust through small victories and shared awkwardness rather than dramatic declarations. This lands for viewers who enjoy character-driven comedy grounded in real emotional stakes. The humor comes from personality clashes and situational absurdity rather than punchlines, making it feel natural and earned.
