The BTS photos make it hard to believe that they'll be playing a divorced couple with their playful expressions and skinship on set. Choi Jin Hyuk's smile was also a breath of fresh air for fans after only watching his serious character on his recent drama 'Heirs'.

PD Yoon Hyun Ki commented, "There were a lot of fun happenings at the set for the teaser. Song Ji Hyo and Choi Jin Hyuk also have good teamwork and even though they were filming until 5 AM, they filmed excitedly. Starting from the teaser video, strong [scenes] will come out."

Song Ji Hyo will play the role of the innocent and gentle nutritionist Oh Jin Hee while Choi Jin Hyuk will play the role of scholar student Oh Chang Min, both of who go through personality changes after divorcing one another. They become practically enemies but end up reuniting unexpectedly after six years apart as interns in an emergency room.

'ER Man and Woman' will premiere following 'Reply 1994' on January 24 at 8:40 PM KST!
