[2][3] Lead actors Lee Sun-kyun and Choi Kang-hee had previously starred together in the 2008 SBS TV series My Sweet Seoul.

In need of money to redeem a treasured family portrait, struggling manhwa artist Jeong Bae takes part in a publishing company's competition for an adult manga with a prize of ₩130 million (US$100,000).

Advised that his big weakness is his story-writing, Jeong Bae advertises for a professional writer and ends up hiring the self-important Han Da-rim, with whom he agrees to split the prize money 50-50 if they win.

Unknown to Jeong Bae, Da-rim recently lost her job as a sex columnist at magazine Hot Girl — edited by her friend Ma Kyung-sun — where she compensated for her lack of experience with men by copying material from the Kama Sutra to the Kinsey Reports.

She finally does, which leads Jeong Bae's friend (and fellow competitor) Hae-ryong, who has secretly bugged his flat, to believe they're having an affair.
