Who's the True Heiress?

Twenty years ago, a maid at the Elikin household accidentally gave sleeping pills to Oliver Elikin's newborn daughter, putting the baby’s life at risk. To avoid blame, the maid swapped the baby with another and left her in the mountains. The abandoned baby was found and saved by Clara, who was burying her own child. Clara named the baby Scarlett and raised her.
Twenty years later, Scarlett works at Elikin Group but faces hostility from Elodie, the daughter of the maid who replaced her. Elodie, now wealthy, falsely accuses Scarlett of theft, humiliates her, and mistreats her.
