The idea of being pursued by a sex-obsessed female ghost in a TV show did not turn off South Korean actor Cho Jung Seok.

Instead, the 34-year-old was drawn to the "quirky and provocative" premise of the romance drama Oh My Ghost, in which a timid assistant chef Na Bong Sun (played by Park Bo Young) transforms into a man-hungry lass when possessed by a virgin ghost who is determined to have sex. The target of the possessed Na's lust is her boss, celebrity chef Kang Sun Woo, who is played by Cho.

Cho and Park were in town to promote the series on Friday. Oh My Ghost! airs on VV Drama (StarHub TV Channel 855) on Sunday at 10pm.

He says of the show: "I heard about the story, about the assistant being possessed by a virgin ghost. The situation itself sounded very interesting."

Park, 25, who has been acting since she was in her teens, agrees with him.

"In most dramas, it's the guys who are seeking love. In this one, the woman is more aggressive," she says.

In real life, Cho, who had starred in the 2012 box-office hit movie Architecture 101, is not so keen on having aggressive women chasing after him - unless they are as attractive as Park.

With a glint in his eye, he says in a mix of English and Korean: "I don't like aggressive girls. But if a girl like Park Bo Young is aggressive (with me), I'll be okay."
