Song Ji Hyo and Choi Jin Hyuk play pranks on each other for new teasers to tvN's new drama "Emergency Couple".

The story revolves around Jin Hee, a dietician who will be portrayed by Song Ji Hyo. She will meet her future husband Chang Min, a medical student who will be portrayed by Choi Jin Hyuk. The couple gets married despite their parents' opposition, but because of various marital problems and incompatibility, they eventually go through a divorce. However, they will be reunited as they both become medical interns in a hospital, and romance will again blossom between the ex-couple.

The first two teasers show the playful relationship between the couple, with Song Ji Hyo deleting the files on Choi Jin Hyuk's laptop, and as a revenge, he writes on her designer handbag. The next teaser shows their more romantic side as they run through the street hand in hand while wearing their wedding clothes.

According to a representative, "Song Ji Hyo and Choi Jin Hyuk are currently filming the drama diligently. While their characters are a couple undergoing a divorce, with only hatred for each other left in their hearts, the actors have a good working relationship off-screen."

"Emergency Couple" will premiere on January 24, taking over the timeslot of "'Reply 1994".
