Roseanne and Chaeyoung Park are known as the infamous twins of Mason Park, the astounding governor of Seoul. However, them having glaringly, similar features is the only thing they have in common. Roseanne Park was at the top when it came to popularity. She has had more boys begging on her feet than she can count. She was a part of various high school clubs and welcomed in many groups. She has a crazy amount of friends, as well as an insane amount of Instagram followers. Not only that, she was dating the visual of BTS, Taehyung Kim. Chaeyoung Park was ordinary compared to her twin, like a tootsie roll amongst a ton of other delicious and unique treats. Boys, popularity, and fun weren't words usually associated with her nor was she ever familiar with. She was an outcast, always hiding in her sister's shadow. However, sudden news of Roseanne's disappearance surfaces and a secret search party is out to find her. Chaeyoung seems to be of good use now, as she is assigned a mission in what is called 'Sister's Substitute.' She must pretend to be her sister in order to save her family's reputation because if the public found out that the governor of Seoul allowed his daughter to go missing, their family's name will be ruined. It was a perfect plan because no one would be suspicious of it, especially since they really didn't know of Chaeyoung's existence. However, there was one rule she mustn't break: don't fall for the guy who was never hers.
