Neo Locke, a scion of a Republican-era elite family, spends a fortune of 4,000 silver dollars to marry his childhood rival Flora Brooks—a woman skilled in both medicine and martial arts—all to settle a childhood grudge over a humiliating haircut and spanking. His plan? To make her life difficult after marriage. But little did he know, he was digging a pit for himself. Now, Young Master Neo’s daily routine involves getting pricked by her silver needles by day and being disciplined by her strict rules at night. The once neighborhood menace has now become utterly devoted to his wife.
