Han-Na (Kim Ah-Joong) is a very big girl with a warm heart. She is also gifted with an unbelievable voice from God. Han-Na has always wanted to be a pop-singer, but due to her appearance, could only work as a faceless singer. She provides the vocals for a popular singer named Ami, a beautiful young lady that can’t carry a note to save her life.
Also, Han-Na is in love with Ami’s music producer, Sang-Jun (Joo Jin-Mo), but it is a one-sided love. One day, Han-Na is invited to Sang-Jun’s birthday party and receives a red dress from him to wear to his party. Han-Na is excited, yet scared. The dress is revealing and quite extravagant. With her very large figure, she is not sure if she could wear such an outfit. She does eventually go to the birthday party in the red dress, but is mortified when petite Ami appears in the same red dress. During the course of the birthday party, Han-Na absorbs more emotional trauma and she simply disappears……..
One year later, after Han-Na’s extreme makeover (major plastic surgery), Han-Na takes on a new identity and becomes Jenny. Jenny has a near perfect body and face. Nobody recognizes her, even her best friend. Meanwhile, the producer Sang-Jun is searching for a replacement singer for Ami, but can’t find anyone close to the talents of Han-na. Han-na as Jenny, now comes back into the picture and auditions for the job. Sang-Jun is immediately floored by her. She has the absolute beauty and that stunning voice. Soon afterwards, her dream that Sung-Jun will fall in love with her, is about to come true. Unfortunately, Ami is now jealous of her and feels threatened by her sudden success. She researches into Jenny’s background and comes up with the truth about her true identity. Will this ruin Jenny’s career?
