He is 11 pounds lighter! Song Chang Ui really got into character for his upcoming role on the OCN television drama Doctor Frost. In the the series, Song plays the main character Baek Nam-Bong, aka Dr. Frost, who is a psychology professor and part-time bartender. Despite the fact that he is brilliant, the head injury he suffered in childhood prohibits his brain from sympathizing with people.  

The Heartstrings actor shed pounds over the course of a month through dieting and boxing to properly transform into his cold new character. The naturally warmhearted star is photographed in new stills on set as the perfect Jack Frost of K-dramas. His blonde hair completes the chilly winter series.
