Inspired by Cinderella, the love quadrangle aspect of four men trying to win the heart of the heroine is an interesting conflict to watch unfold.
Eun Ha-won is a bright high school senior who dreams of becoming a teacher. Unfortunately, she loses her mother in a tragic car accident and when her father remarries, a cruel stepmother moves in and steals Ha-won's college tuition. Ha-Won works various part-time jobs to pay for her upcoming university tuition fees.
One day, she meets an old man who convinces her to move into a gorgeous mansion with three equally gorgeous men, who also happen to be billionaire cousins and heirs to the Kang family fortune. Between the rebel-minded loner Kang Ji-woon, playboy money machine Kang Hyun-min and the super-sweet singer Kang Seo-woo, Ha-won finds herself in the middle of the hottest love quadrangle to ever befall a modern fairy tale princess.
