A simple tale of a rich-poor young female children who are in the same school in the end both found out that they were switched at birth. Then the story unfolds to something that is heartbreaking. You will later on see the struggles of the 2 female children and how they both live their separate lives, especially the poor female child.

It is a emotional heavy roller coaster experience as it heavily focused on the character that's played by Song Hye Kyo & the rivalry of the 2 men that are both her love. Her life ended tragically and in the end (spoiler) the last person who got to spend time with her is Joon-suh. It was a tale of family drama at first but grew towards to melo-romance in the end. The forbidden romance was built up nicely especially towards the second half and the anger/resentment of the original female child had interesting development. Though how i wish the family dynamic was played alot better.

The performances that left a good impression in me were Song Hye Kyo & Won Bin. They simply understood their character & the thought of grief.
