Watch: Im Soo Hyang And ASTRO's Cha Eun Woo Are A Goofy Duo In "My ID Is Gangnam Beauty" Making Video

JTBC’s “My ID is Gangnam Beauty” released a new behind-the-scenes video!

The video starts off with ASTRO’s Cha Eun Woo giving a soft smile and waving gently to the camera he just discovered. Then Cha Eun Woo and Im Soo Hyang rehearse a scene where they are trapped in the chemistry major’s gathering room. Im Soo Hyang attempts to open the door, but it easily opens with one twist of the doorknob, making Cha Eun Woo laugh. She comments, “It just opens!”

As the clip progresses, a crew member holds up a shirt with a picture of the bare top half of a male’s body and says, “This is a shirt that no one can wear.” Im Soo Hyang tells Cha Eun Woo, “Kyung Suk [his character name], wear this.” He curiously holds the shirt against him, and Im Soo Hyang pinches the shirt by his side so that it fits snugly and comments, “T-shirts are supposed to show off your waist line.”

Later on, Im Soo Hyang has to film a scene where she puts on a shirt in a tight space against the wall in a limited amount of time. Once the filming is over, Cha Eun Woo comments, “Let’s do that on ‘Ask Us Anything’ next time. Changing clothes in a tight space.”

During break time, the two of them joke around with each other. Cha Eun Woo pretends to have a heart attack, and Im Soo Hyang mimics him. When it looks like he’s losing air, she tilts his jaw back to straighten his throat. Then a crew member asks Cha Eun Woo if he’s hungry, and he replies, “I’m nervous.” The crew member jokes for him to do something about his “friend” in his stomach, and Cha Eun Woo laughs in response.

Im Soo Hyang and Cha Eun Woo aren’t the only goofballs on set. Kwak Dong Yeon loves to also play around with the cast and crew off the set. When Im Soo Hyang attempts to drag Kwak Dong Yeon off the set with her, he comments that he’s going to stay a bit longer. Jo Woo Ri points out he’s only staying for the making film camera, and Im Soo Hyang tries to make him leave with her again. However, Kwak Dong Yeon refuses to leave as he randomly says, “I have something to do. We’re talking about rising sales.”

Im Soo Hyang appears in front of the camera and claims, “The making film is mine.” Kwak Dong Yeon shakes his head and declares, “No, it’s mine.” Jo Woo Ri can’t help but laugh at their cute quarrel in the back.
