Jung Eun Chae will play veteran detective Joo Hye Ra, Jin Yi Soo’s new partner. The highlight video opens with Jin Yi Soo aboard a flight. Jin Yi Soo timidly tries to push back, but his resistance is quickly shut down. However, Joo Hye Ra remains just as confident as she declares, “There’s no such thing as a perfect crime.” The video ends with Jin Yi Soo boldly proclaiming, “Just watch how far I can go.”
