The once unshakable hierarchy at Cheongdam International High School is now fractured!
Kim Hye In, the witness of two murders, is the first member of Diamond 6 from an underprivileged class. Baek Je Na, the Queen, whose world is endangered after the crumbling of the succession structure, strained friendship, and suspicion of her as the murderer. Kim Hae In, the Cinderella who returns dreaming of revenge, not love. Seo Do Eon, who is in confusion after facing the tragic truth of what he has believed as love. Min Yul H,ui who chooses to embrace thorough unhappiness if happiness is unattainable. Park U Jin is full of selfishness and an inferiority complex. And Lee So Mang, an unexpected mastermind.
And now, a powerful new face enters the scene, shaking everything up! Once again, Hye In and Je Na find themselves at the center of it all. Will they make the same choice, or will they choose differently?
