To start, I've watched this drama over and over and even went so far as to buy the DVD (which I RARELY do). I loved all the characters, especially Cinderella and her "four knights" (tho truthfully there only seemed to be 3). Park So-dam as Eun Ha-won, the lead female character, was spot on! Not too cutesy, not too brassy, she truly represented someone who despite her struggles was able to stand alone, independent, and was able to still find the joy in life. The 3 Knights: Jung Il-woo as Kang Ji-woon, the middle cousin, was terrific! The right amount of handsomeness, arrogance - but because of past hurts not because he thought of himself as better than anyone - and fun! And he had great chemistry with Park So-dam. Ahn Jae-hyun as Kang Hyun-min, the eldest cousin, was hilarious! So full of himself, but also dealing with deep hurt inside. He and Park so-dam had sparks & their relationship was such fun to watch. Then there's Lee Jung-shin as Kang Seo-woo, the youngest cousin, a popular singer-songwriter and top star. His was the most "real" relationship with Park So-dam, IMHO, and they sparked like brother & sister. He was such a good guy - and he and his Mom together were PRICELESS! Choi Min as butler Lee Yoon-Sung was so cool but so funny when confronted with Eun Ha Won's independence! And I LOVED Ms Beolgyu who was the cook & maid. The guys who played Kang Hyun-min's friends were perfect, too. LOVED THE ENTIRE CAST! This is funny, light, engaging & just plain enjoyable to watch! HIGHLY RECOMMEND!
