Top Korean actress Ko Hyeon-jeong is set to star in a new television drama alongside Hallyu star kwon Sang-woo, according to local media reports on Thursday.

The actress has decided to appear in the drama tentatively titled "Big Thing" in English ("Daemul", "The Substitute"), after long and hard consideration, the reports said.

Ko's contract, however, is said to include a clause which stipulates that Kwon must play the male lead.

Kwon, who has been contemplating on whether to shoot the series for two years, has reportedly given a verbal agreement to do the show and is currently working out the details of his contract.

"The Substitute", based on a comic book series of the same title by Park In-kwon, is about a first-class gigolo (played by Kwon) who helps a human rights lawyer (played by Ko) achieve her dream of becoming Korea's first female president.

As a former Miss Korea runner-up, Ko rose to stardom after starring in 1995 hit TV series "Sandglass" and made headlines after marrying Samsung Group Chairman Lee Kun-hee's nephew Chung Yong-jin.

She resumed her acting career in 2005 after getting a divorce and fully regained her reputation as Korea's top actress last year, receiving the grand prize at the 2009 MBC Drama Awards for her role in the smash hit TV series "Queen Seon-deok".

Shooting for "The Substitute" is scheduled to begin in May.
