The Marquis Mansion is a deep residence, and every step is in jeopardy. Seventeen-year-old Liu Luoluo was originally the down-and-out legitimate daughter of a scholarly family. In order to protect her young brother, she was set up by her stepmother to replace her elder sister and marry the Marquis of Yongning, Gu Yanzhi, who was nearly fifty years old and had been sick all year round. She became the "little grandmother" that everyone in the capital laughed at - half a year younger than her husband's legitimate son, Gu Jingchen, and only sixteen years older than her step-grandson, Gu Nian'an, who was just one month old. When she first entered the Hou Mansion, she faced a husband who looked on coldly, a rebellious stepson, an aunt who stared covetously, a sideline who coveted the family property, and a stepmother and clan sister who were scheming behind the scenes. After losing his youth and cowardice, Liu Luoluo relied on his own efforts to hide his edge, stick to the bottom line, recruit loyal help, resolve the crisis in the house fight, make friends with his ex-daughter-in-law who was neglected by his stepson, support the virtuous step-daughter-in-law in her rightful place, and unexpectedly awakened the heart of Yongning Marquis that had been frozen for many years. From being a chess piece at anyone's disposal, to being in charge of the prince's palace and protecting the people around him, Liu Luoluo used gentleness and tenacity to find his own way of being a "little grandmother" in a high-ranking family with strict rules, and also unlocked a series of warm bonds with her husband, step-son, and step-grandson.
