All messed up

The whole plot is messed up. How can a girl with low morals get away by being accepted by a whole educated well to do family so easily. Characters and the storyline is portrayed, in my opinion, as extremely shallow. Failed to arouse any sympathy for any of the characters at all. No real situations like this can happen, really unbearable to watch. Would strongly not recommend this. Have watched many Korean dramas, but this happens to be the worst ever. In fact, this put me off Kdramas for a short while.
