Eun Ha Won is a bright college student who dreams of becoming a teacher. Unfortunately, she loses her mother in a tragic accident, moves in with a cruel stepmother, and has no money for her education. One day, she helps an old man and as fate would have it, moves 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, Eun Ha Won finds herself in the middle of the hottest love quadrangle to ever befall a modern fairy tale princess. Rounding out the mansion's chaebol lifestyle are Lee Yoon Sung, who serves as the cousins' handsome bodyguard, and Park Hye Ji, a gorgeous girl who has her own interests in the Kang family and is not above manipulating one cousin to get closer to another.

This drama is so good. I give it 8/10. Although it is a bit cliche with the poor woman and rich guy story, but it's surprisingly good. You will definitely face the second male lead syndrome because I definitely am xD. But as the story goes on, I can't help but falling in love with the main lead. Their chemistry is great
