Song Ji Hyo looked simply gorgeous even in plain scrubs and minimal makeup. Even though she looked a bit tired from her busy filming schedule, the actress still put on a big smile throughout like the good sport that she is. 

The actress immediately captured viewers' hearts with her comedic acting with the drama's premiere last week, so naturally the anticipation is rising for the upcoming episodes.

Oh Jin Hee (Song Ji Hyo) and Oh Chang Min (Choi Jin Hyuk) will begin their new life as interns at the ER (emergency room) on the 31st at 8:40 PM KST!
