SPIOLERS AHEAD!!!!!! the story was well plotted and acted for a plot that only had a few epiodes frankly to be honest the only thing that i didn't like about it was the fact that it had only 12 episodes which gave me dram fever as to it was very interesting. the story was just the usual kwon shi yeon is an overweighted teen who is bullied because of her weight and envies her sister kwon si ah who is a member of girl group miracle girls and is known for her for her beauty and her, when shi yeon comes upon a mysterious tarot and gets a wish and she wish for shi ahs body OK THAT ENOUGH SPIOLERS kwon shi yeon played by hong yoon hwa was ell fit for the role as she was well not to offend her but she was fat enough for the role and had the charisma but kwon shi ah's (kim na hyun) atitude was best fit for shi yeons visual so if the really switched bodies forever there might be a benefit shi yeon can lose weigh because shi ah goes on diet's alot and shi ah can have a better vioce and not be tone deaf
