Emerald Cardenas only went to school for one reason:
To meet the rumored real Prince , Prince Lorenzo Saavedra. Surely he would make her boring life interesting. 
She didn’t make a mistake. He indeed made her life interesting. He is not the typical boy next door and prim and proper prince. 
He is arrogant and an asshole. 
He isn’t even charmed by her beauty.
She wanted to play with him but it seems that he wanted to play with her too. 
They are in a game. 
The one who falls in love is the loser.
