Ha Ji Won and Lee Jin Wook believe it's possible to fall in love with a friend.

12. Lee Jin Wook dated Air City costar Choi Ji Woo

They became good friends after filming Air City (2007) and hanging out with mutual friends. When they confirmed the relationship in 2009, people thought it was cute they became an actual couple because Lee Jin Wook had previously said Choi Ji Woo was his ideal girlfriend type while filming Air City. For other people, it was a surprise that Choi Ji Woo (34) was older than Lee Jin Wook (28). Unfortunately, in 2011, 3 years into the relationship, they were separated due to many reasons, including Lee Jin Wook's military duties.
