JTBC's ongoing drama "Moments of 18" has released new behind-the-scenes footage!

The making video lasts for about four minutes, and starts with the cast gathered around in circles as they film the part where they have to join a specific number of people to form a team.

Standing at the center, the director explains how Ong Seong Wu, Kim Hyang Gi, Shin Seung Ho, and Han Sung Min will arrange themselves to create a love square.

The clip then transitions to the director telling Kim Hyang Gi that she will pair up with Han Sung Min, Sung Min's face brightens up as she hugs Kim Hyang Gi and states, "Come here!" On the other hand, Ong Seong Wu and Shin Seung Ho gaze blankly at each other, making everyone burst into laughter at their surprised reactions.

After every take, the cast checks how the video turned out and can't help but laugh while watching it. Afterward, the characters ready themselves for the next scene where Ong Seong Wu protects Kim Hyang Gi from a balloon filled with flour and confetti.

Before filming, the director guides Ong Seong Wu on how to properly block Kim Hyang Gi and also tells Hyang Gi what to do as Seong Wu protects him.

Baek Jae Woo then fakes to pop the balloon in slow motion, and Ong Seong Wu pretends to punch his face and blocks Kim Hyang Gi once more. Baek Jae Woo laughs as he comments, "You're too slow."

The recording for the scene begins, and the cast immerses into their characters. They start counting down, and once it reaches one, Ong Seong Wu hurriedly went at the back of Kim Hyang Gi to cover her from a shower of flour and confetti.

The director then calls the end of a successful scene, and everyone cheerfully applauses. Ong Seong Wu walks closer to Kim Hyang Gi and takes bits of confetti off of her hair while the other actors try to get him cleaned as well.

"Moments of 18" premiered on July 22 this year, 2019, and is broadcasted every Monday and Tuesday at 9:30 p.m. KST. This drama is Ong Seong Wu's first lead role.
