To save her gravely ill younger siblings, Dani, a girl from the lowest class, signed a death indenture to sell herself into the Prince Guangling's Mansion. To avoid trouble, she deliberately disguised herself with an ugly appearance, only wanting to work steadily to earn money and support her family. Wanting to live a peaceful life, she was instead mistakenly chosen by the cold-natured Heir Lou Xuanyi to serve in the mansion. Clumsy and awkward, she caused quite a few hilarious farces and unexpectedly saw through a hidden malicious plot within the mansion. On one side are the undercurrents and scheming factions of the prince's inner courtyard, and on the other are her impoverished family members she cares about. Relying on sheer brute force and clever courage, the ordinary girl grows step by step amidst the perilous prince's mansion, beginning a life intertwined with laughter and tears.
