In the next scene, Park Seo Joon and Park Min Young are seen preparing to shoot a scene where he is about to give her a surprise back hug after waking up from a short nap. After filming said scene, Park Min Young asks if the whole thing looked force, to which the director said it didn't. Park Seo Joon then proceeds to tell everybody that Park Min Young was definitely carried away by his embrace, causing everybody to burst into laughter.

Adding to the list of bloopers is Park Seo Joon's attempts to make Park Min Young call him "oppa." The actress goes with it and plays the part perfectly despite the whole awkwardness. When the actress' character's sisters, played by Heo Sun Mi and Baek Eun Hye, call her name, the actress involuntary answers "What?" which wasn't on the script at all, causing another round of laughter.

All in a Days' Work

While the actors have fun on set, the video also shows how they can be very serious especially when it comes to intense scenes. In one kissing scene, the lead characters are shown monitoring their kiss in the video. Watch the What's Wrong with Secretary Kim BTS clip below.
