The Imperial Daughters of Fairy Grove

Phoenix Blaze is not sure whether she can be a good ruler. She is the eldest daughter of Supreme Lord Remus and heir to the throne of Fairy Grove. At first she thought it was easy. But as the years went by, she realized taking the throne is not as easy as she anticipated.
With the addition of her youngest sister Sophia Alice getting admitted into CAST as its lieutenant and Prince Brandoneus of Diamond Valley hitting on her, Phoenix's life can't get any crazier.
Kia Waters thought she would have it all: Romance, her father and elder sister's love and attention, popularity, and a happy life, until her younger sister Sophia Alice came into the world. Her brat of a sister took everything Kia dreamed of having, and she hates her for it.
Sophia Alice is living in between two worlds. In one world, she is an outcast, and no one likes her. In the other, she is loved by everyone. Because of that, she feels insecure. But when she joins CAST and falls in love with Prince Brandoneus of Diamond Valley, her entire life changes.
