Pretty much the whole plot is Eun Hye's character is a regular school girl who all of a sudden is set to marry the Crown Prince of S.Korea because of her grandfather. Ji Hoon, who has a relationship of his own, but doesn't really go against the will and the two end up marrying. So really most of the episodes are of them two leads slowly starting to get along. But of course in the way are Ji Hyo & Jeong Hoon's characters, creating the fan favorite love square. My only problem with this drama was the length. Though I did like it a lot, this drama probably could've been 20 episodes and would have still been good. A few issues and misunderstandings were dragged out longer than should have but that's what you get with Korean dramas. I loved the whole cast. I felt that Eun Hye's acting at time was a little..much but it was necessary for Ji Hoon's character, so i couldn't really be annoyed. I think my favorite actor was Kim Hye Ja (Queen). She was so adorable! Her sweet attitude and voice was perfect for such a role. Supporting cast was great too. I thought everyone was casted perfectly. Music was fine, Perhaps Love and the instrumentals were nice to listen to ~ I still do rewatch this drama from time to time (since I have the DVD) but I don't think I could sit through episode 1-24 without skipping parts. One full time was enough for me. But I feel this is one of those "classic" dramas most drama watchers come across at some point, so at least give it a try!
