After spending years away from home because of school and work, the young heiress finally comes back—only to find the maid's daughter living like the princess of the house.
The girl wears clothes from her closet, uses her jewelry, bags, and luxury goods, calls the heiress's grandmother “Grandma,” and acts as if she and her mother are the real owners of the family home. Spoiled and arrogant, she has completely blurred the line between servant and master.
Even after the real heiress returns, the maid's daughter refuses to step back. She plays the victim in front of the kindhearted grandmother, tries to push the heiress out, and shows two completely different faces depending on who is watching.
So the heiress stops arguing and starts setting a trap. Step by step, she gives the imposter enough room to expose who she really is—until the mask finally comes off in front of everyone.
