Watch: Jeon Mi Do Keeps An Impressively Straight Face Through Jo Jung Suk's Puns And Funny Antics In "Hospital Playlist 2"

tvN has released a behind-the-scenes video from episode 7 of “Hospital Playlist 2”!

The video begins with Jo Jung Suk wholeheartedly embracing his character Lee Ik Joon’s reputation for being an “insider” at Yulje Hospital. (In Korean, the slang term “insider” can mean someone who has a wide circle of friends and acquaintances and is “in” all the right circles.) He leans over the railing to talk to someone down below and shakes someone’s hand with warm friendliness.

In one particular scene, Lee Ik Joon is riding down with Chae Song Hwa (Jeon Mi Do) on the escalator and is supposed to run into a cleaning lady coming up on the other side. However, the actress who plays the cleaning lady pauses halfway, messing up the timing that the two escalators are supposed to cross. Even though the take will have to be re-shot, Jo Jung Suk stays completely in character as he starts to walk up the escalator instead to carry on the conversation. The entire production staff on set bursts out into laughter, but Jeon Mi Do keeps an impressively straight face by Jo Jung Suk’s side.

Jo Jung Suk continues to make the production staff laugh as he tries to act cute for the camera. He plays up his “cuteness” further and further, raising his hands to his armpits when the director says that the camera can’t capture anything below his chest, and even makes the pun, “I have no ears.” (The word for “cute” in Korean can sound similar to the phrase “no ears”). Only when he leans into his pun, pretending to have dropped his ears on the floor, does Jeon Mi Do give in with a laugh and playfully slap him on the back in retaliation.

The next scene shows Shin Hyun Been and Yoo Yeon Seok filming their cute mini-date at the hospital. Shin Hyun Been messes up a line because she has put too much food in her mouth, and as soon as the director says “cut,” she cringes with embarrassed laughter. She tries to explain, but the production staff note with affection, “We can’t even hear her excuses through the food in her mouth.”

In the next scene, it’s Yoo Yeon Seok’s turn to mess things up. When Shin Hyun Been comes up to his car, he’s supposed to lower the window, but he can’t find the right button and ends up turning on the windshield wipers instead.

Jung Kyung Ho and Kim Dae Myung get their fair share of teasing from the director. In a scene where Jung Kyung Ho’s character Kim Jun Wan is warning Do Jae Hak, “Don’t fall in love with me,” the director watches the first take and then observes, “Since Jun Wan is pretty lonely now, how about we film it as if he wavers for a slight second?” Jung Kyung Ho is surprised and takes a moment to figure out the situation, and then films the take exactly as the director suggests, with a look in his eyes that the production staff describe as “straight out of a romance drama.”

Kim Dae Myung, on the other hand, is just walking down a hallway, but he absentmindedly keeps tapping the walls with his other hand as he looks down at his cell phone. Finally, the director blurts out, “Stop that,” much to everyone’s amusement.
