Welcome to Olivia's Magic Jewelers

Synopsis

After coming home one day after working herself ragged, Olivia finds her engagement called off by her fiancé. What's more, her adoptive sister claims Olivia's jewelry designs as her own while Olivia's adoptive family chases her out of her own home and store. Having lost everything, she tightly grips a letter of introduction her late father wrote and heads to the capital, all alone. There, she works hard and manages to start her own shop. This is the story of a girl who hits rock bottom then climbs her way back to happiness through her own hard work, showing the people who took everything from her that she can't be kept down.
