200 Pounds Beauty (미녀는 괴로워 - Minyeoneun Goerowo) is a 2006 South Korean comedy film based on a Japanese manga, Kanna-San, Daiseikou Desu (カンナさん大成功です!) by Yumiko Suzuki. The literal meaning of 미녀는 괴로워 is 'Being Beautiful is Agonizing.' The story tells the tale about an overweight girl who undergoes extreme plastic surgeries to become a pop sensation.

The film was a financial success, earning approximately $45 million against its $4 million budget. It also received large critical acclaims, winning Grand Bell's Best Actress for Kim Ah-jung and Best Cinematography together with nominations for Best Film and Best Director.

Han-na is an overweight phone sex employee and a secret vocalist for Ammy, a famous pop singer who actually lip syncs as she cannot sing. Instead of being famous for her own amazing vocal talent, Han-na hides behind Ammy's performance stage and sings during Ammy's concerts, and records all of Ammy's songs. One day, Ammy ungratefully humiliates her in front of the music company's director Sang-jun during his birthday party, knowing full well that Han-na has a crush on him. While crying in the bathroom, Han-na overhears Sang-jun telling Ammy that even though they are just using Han-na for her voice, they must be kind to her so she will not walk out on them. Heartbroken, Han-na attempts suicide but is interrupted by a phone call from one of her phone sex regulars who happens to be a top plastic surgeon. She decides to get head-to-toe plastic surgery instead. The surgeon at first refuses to operate on Han-na, but Han-na threatens to blackmail the surgeon by telling his wife about his calls. Then, Han-na makes a moving speech that she does not want to undergo surgery merely to be beautiful, but for the sake of love and as a boost in confidence, and the surgeon is deeply moved. Han-na puts herself in seclusion for a year as she recovers from the changes.
