Hidden

She was once the empire’s sharpest hidden blade. Reborn, she just wants to lie low and slack off, but she’s forced to take over the hopeless mess left behind by the original owner of her body: a good-for-nothing husband, jealous sisters-in-law waiting to pounce, a young sister-in-law of marriageable age, and a regent prince whose dangerous curiosity about her knows no bounds. So she has no choice but to keep her secret identity under wraps while cleaning up the mess, and casually turn the whole world upside down.
