Watch: Park Seo Joon, Kim Da Mi, And More Display Energetic Chemistry On The Set Of "Itaewon Class"

JTBC’s “Itaewon Class” has dropped new making videos!

In the first clip, Park Seo Joon and Kim Da Mi meticulously discuss how they should approach an upcoming scene. Kim Da Mi describes her vision, which they instantly bring to life. Park Seo Joon shares his concerns, saying, “You’re doing it like you always have, but how should I do it?” Kim Da Mi explains, “I did try to act seriously at this part, though,” to which Park Seo Joon adorably replies, “I thought you were really cute and good. But, I don’t know to what extent I should react.”

Just before cameras start rolling again, he sweetly asks Kim Da Mi, “You aren’t uncomfortable, right?” to which she assures she’s okay. Once they start filming, Park Seo Joon, along with the entire set, cannot contain their laughter at Kim Da Mi’s adorable acting.

They film the next scene at the hospital, where they continuously discuss directions for the scene. They also practice how to perfectly time Park Seo Joon’s interruption into Kim Da Mi’s line, with Park Seo Joon jokingly saying, “Don’t go in right away. Leave me some space to interject.”

The next video features rehearsals with Park Seo Joon and Kwon Nara. As Kim Da Mi flees from seeing the two together, Park Seo Joon follows after seeing Kim Da Mi with Kim Dong Hee, leading them all to giggle silently in a tight stairwell until the director yells “Cut!”

Kim Dong Hee shyly puts out an announcement looking for a “missing” Ryu Kyung Soo, describing him as “29 years old, height of around 170 centimeters, a decent weight, and short hair often covered with a beanie.” Instead, his on-screen brother Ahn Bo Hyun appears, surprising Park Seo Joon and Kwon Nara on set. They ask him about his changed appearance and recent haircut as he explains he came early to film.

The final episode of “Itaewon Class” airs March 21 at 10:50 p.m. KST.
