Petty Romance (2010)

Synopsis:

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 ₩130 million. 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, where she compensated for her lack of experience with men by copying material.
