One morning, 16-year-old Sey's world is turned upside down when her mother announces she's moving to Italy to finish her novel. She's made arrangements for Sey to live with her friend, Meja, and Meja's creepy son, Terry. Not exactly Sey's ideal living situation, but she has no other choice. Sey has a killer crush on a teacher named Mr. Cho, and she's beyond shocked when she learns that Terry knows him well ... VERY well. And so begins I.N.V.U. (I Envy You) - a hip, moving, topsy-turvy look at the lives and loves, trials and travails of 4 teenage girls.

When Yuna Lee's mother moves to Germany to pursue a music degree, she's left to stay with her father, a university professor, and her three older brothers, who are fiercely overprotective of her.

During her summer vacation, she visits her mother in Germany, where she falls off a cliff and is rescued by Rieno, an 18-year-old knight living in the land of Phantasma. Rieno makes a deal with Yuna: If he saves her life, she must come with him and become the Queen of Phantasma.

After agreeing, she goes back home, only to return to Germany some months later, and is whisked away to Phantasma by Rieno. Now, she must cope with being the Queen of Phantasma, while forgetting the world she came from.
