Star's Lover (2008)

Star's Lover is a warm-hearted tale of a woman being pursued by four men. When bookish university professor Kim Chul Soo runs out of money and is forced to accept help from his ex-girlfriend, he will do anything to pay her back. Opportunity knocks in the form of a ghostwriting offer from the management agency of Lee Ma Ri, the most popular actress in Korea. Caught between his convictions and his need for money, Chul Soo reluctantly agrees. The travel diary he writes under Ma Ri's name becomes an instant bestseller, but it ends up bringing her some unwanted attention from a famous photographer. Afraid she'll be discovered for not writing the book, Ma Ri commissions Chul Soo to coach her in Japanese culture and travel as more suitors fall into place. Ma Ri and Chul Soo grow closer, and soon Ma Ri finds herself caught between four men.
