After amassing a colossal debt, Curo Kazamiya's father fled into obscurity to avoid legal action amid mounting pressure. With his mother gone years earlier, Curo had no choice but to pledge himself to Miisu Hakuryuuin, a estate owner and entrepreneur of great wealth. To the boy's astonishment, his new patron proved to be a master who did not intend to punish him for his father's transgressions in any way. Instead, he presented Curo with a chance to serve and settle the debt through his toil with dedication. Curo accepted readily, feeling fortunate to sidestep a far graver outcome than expected in practice. Yet he remained unaware that Miisu expected him to undertake duties beyond those of a typical servant in the household.
