Suji is a marathon athlete content with spending her life in 2nd place. But after her twin Suah, Korea’s top celebrity,
passes away in an accident, Suji has lost the light in her life. Just like that, a year goes by. Suji has stopped running, working part-time jobs instead.
Meanwhile, Youngjoo receives the shock of her life. Her fellow trainee was selected to take Suah’s place as the new member of Korean girl group Red Queen.
To make things worse, her agency went belly up. An old man with a cat suddenly appears before Youngjoo and her friends, introducing himself as their new agency’s CEO.
