Justin is the commander of the Order of the Knights, a man whose arrogance, ruthlessness, and cold demeanor make him an object of terror for everyone around him. One day, he suddenly recalls his past life: he was a college student and the eldest of eight brothers, a young man who spent his days tirelessly caring for his seven younger siblings after their father passed away. With that flood of memories comes a horrifying realization: he is now living inside the world of a light novel he once read, and his role is that of a villainous knight commander whose cruelty is so extreme that he is destined to be executed by the story’s hero. Facing a one-way route to ruin, Justin vows to change his fate. Drawing on the nurturing, maternal instincts he honed as the big brother of a large family, he resolves to reform the undisciplined members of his knightly order. But his efforts to impose good behavior and proper manners on his rough-and-tumble subordinates set off a chain of events that ripple far beyond the barracks, shaking the very foundations of the kingdom. What begins as a desperate attempt to avoid a death sentence evolves into a story of redemption, as the former villain commander uses kindness, domestic wisdom, and an unshakable sense of responsibility to transform his reputation, his followers, and the world around him.
