Jo In-sung
At 1:00 a.m. on June 19, 2014, the van Gong Hyo-jin was riding became involved in a three-vehicle rear-end collision with two trucks; she was on her way back to Seoul after filming in Yongin, Gyeonggi Province. This resulted in a left arm fracture, a knee injury, and scratches on Gong's face. After recuperating, she and co-star Jo In-sung later left for a shoot in Okinawa, Japan where their characters go on a romantic trip. Gong's fractured arm was incorporated into the story.
