Plot
Twinkle, Twinkle is a light, cheerful, and heartwarming family drama that tells the success story of Han Jung-won (Kim Hyun-joo), a workaholic career woman who is determined to make her own way in the world without the help of her family, which has garnered considerable wealth from their publishing company.

But what Jung-won doesn't know is that because of the hospital's negligence, she was switched at birth with another baby, Hwang Geum-ran (Lee Yu-ri). The identity swap resulted in the two girls being raised by families of different wealth and status, and living a different fate.

When Geum-ran learns the truth, she sees it as a way to reverse her poverty-stricken circumstances. But even after being restored to her rich biological parents, Geum-ran's bitterness makes her consider Jung-won her rival, and she continues to torment her.
