I am profoundly disappointed, the leading actors / actresses have talents but they performed so poorly in this "Cinderella and the Four Knights" K-Drama series. I only tolerate "Cinderella and the Four Knights" when High Schooler Eun Ha Won and Cousin Kang Ji Woon / Han Ji Woon characters are smiling, their smiles brighten the screen. However, there are no on-screen chemistry at all for all characters in this poorly written story. Cousin Kang Hyun Min character is the heir of Chairman Kang, but he does not even work and only lounges in the Sky House and dating / dumping girls. What a complete loser. I love the younger cousin Kang Seo Woo that is productive as a singer and composes songs. I am so disheartened when cousin Kang Ji Woon stops working as a mechanic and looks so idle for the rest of the series. Hoping to see these promising actors/actress with strong talent to be in well written K-dramas series next time.
