A Yue from Mudbrick Alley in the capital has had a life more bitter than the fiercest medicine. Her father is a drunkard and gambling addict who beats his wife and children at the drop of a hat. Her sick mother lies in their crumbling house, coughing up blood nonstop, while her two younger siblings are so hungry they're skin and bones.
Just across the wall stands the Jing'an Marquis's residence. The noble young lady Jiang Wanyue lives in luxury, but beneath her beautiful face lurks a living devil. She treats the maids' lives as worthless, often pulling out her hairpins to torture and kill them.
No one knows that A Yue, who is as lowly as mud in Mudbrick Alley, has a face exactly like that of the marquis's daughter, a beauty beyond compare.
On a freezing, snowy night, her gambling-addict father tries to steal the copper coins meant to buy medicine for her sick mother and kicks A Yue into the corner of the broken stove. The original owner dies with hatred in her heart. When she opens her eyes again, a modern soul has suddenly entered her battered body. Facing a cruel world and the powerful family's schemes soon to come knocking, she wipes the blood from her forehead, a cold glint flashing in her eyes.
