"Emergency Couple" actor Choi Jin Hyuk helped out his ex wife Song Ji Hyo.

On the most recent episode of the cable channel tvN's drama "Emergency Couple," Oh Chang Min played by Choi Jin Hyuk, announced that everything was his fault to cover up the mistake of Oh Jin Hee, played by actress Song Ji Hyo. Previously, Oh Jin Hee with the help of Oh Chang Min conducted a surgery on a patient in an emergency situation, who ended up passing away.

As the patient died during the operation, the family of the patient filed a lawsuit against the doctor Oh Jin Hee, and the problem got much bigger. Finally, the doctors had a meeting to see who was at fault. After doctors asked the responsibility of the interns in the emergency room, Oh Jin Hee was asked to appear in the meeting room. When Oh Jin Hee reluctantly opened the door of the meeting room, Oh Chang Min appeared out of nowhere and helped her out. He said, "It was an inevitable situation. The patient was in such a great danger. I do not know much about the circumstances surrounding the operation, but I was the intern who conducted the operation to the patient," and announced that the patient was his responsibility. When the doctors said, "How are you going to be responsible for this? Are you ready to resign as a doctor if needed to?" Oh Chang Min said, "If that is the necessary step, I will."
