Watch: Kim Soo Hyun, Seo Ye Ji, And Oh Jung Se Crack Up While Filming "It's Okay To Not Be Okay" In Medieval Costumes

tvN has released another behind-the-scenes look at tvN’s “It’s Okay to Not Be Okay”!

The clip focuses on the scene where Kim Soo Hyun has to rescue Seo Ye Ji from the “villainous” Oh Jung Se in the medieval ages.

Oh Jung Se appears in his costume with a full beard, exuding an evil aura, and the staff members burst into laughter. Seo Ye Ji comments that he looks like a completely different person, and Oh Jung Se purposely speaks to her in a low voice to match his new appearance.

Filming starts, and Oh Jung Se drags Seo Ye Ji outside the set. Kim Soo Hyun, who is behind them, comments, “[We have to go through] the door!” Oh Jung Se’s eyes widen in shock, but he snarls and pulls Seo Ye Ji to the correct location. While acting, Kim Soo Hyun ends up on the floor, and Seo Ye Ji asks, “Why did you fall?” In bewilderment, Kim Soo Hyun quips, “Hyung (Oh Jung Se) threw me!”

Next, the three actors film the part where Kim Soo Hyun and Oh Jung Se have a sword fight while Seo Ye Ji is on the floor as a damsel in distress. Kim Soo Hyun and Seo Ye Ji can’t stop laughing at Oh Jung Se’s ad-libs and exaggerated actions. They attempt to film again, but this time, Oh Jung Se isn’t able to pull his sword out, and Kim Soo Hyun falls onto his knees from laughing too much.
