The plot itself was good, but I can say I was completely disappointed in all of the main characters. For starter Eun Jo. I really liked her in the beginning, but I quickly could not stand this character. It is truly sad when society sees her behavior as acceptable. She was completely rude to everyone for no reason whatsoever. She had no regard for others feeling, always acting so high and mighty until she needed someones help, and even after getting help could not utter a simply thank you. Hyo Seon simply annoyed me. I orginally thought this girl was incapable of anything and then I realized one simple thing about her. She behaved the way she did simply because no one cared. Her father gave Eun Jo all the attention and everything she wanted and she was just simply in the dark. I believe this girl knew more than she acted like she did but never cared to act on them because of her concern of others feelings. The funny part was when she tried to be mean and it always backfired because she was trying to be who she was not. i wanted so bad for her to get some type of backbone and take control of her fathers compnay, not let her evil stepmother and stepsister have some much power over the company and her.Ki Hoon was in short an ass. How can anyone knowing watch someone he loves hurt another person he cares for as a sister? I find it odd that everyone on this show knew Eun jo was wrong but consider it acceptable for her to act that way. I hated that he scolded Hyo Seon simply because he knew Eun Jo was wrong and all that she had taken from Hyo Seon, yet treated her like it was her fault.Eun Jo mother is in a category of her own and horrible no where near describes this woman.Mr. Goo saddens me. He watched these people downgrade his daughter and did nothing. i was so sick of him doing that and in the end did not leave his daughter even a means of having something for herself. I hated that at any point in time her stepmother could have just kicked her out without nothing.
