Son Seung-hee, the director of IVE's 'I AM' music video, appeared on MBC FM4U's 'GOT7 Youngjae's Close Friend'.

Director Son revealed her reason for leaving "Thank you to the members who followed me well, especially Won-young." 

"This is a story that has never been officially told. Jang Won-young was injured while dancing and had to receive seven stitches." said director Son.

She continued, "This is the first time I've been so surprised at a film set. Only two scenes remained, but I didn't think I could film them. Two days in a row, we went to the emergency room to have her arms stitched up, and then I filmed all the scenes. Jang Won-young showed no signs of inconvenience," she said.

As Director Son praised Jang Won-young, she said, "If I were that age, I would have been obvious. There is choreography that involves stretching your arms out, and even watching it made my arms hurt."

She added, "It was painful to see her performing powerful choreography. However, she was so professional in monitoring the music video. During the shooting, it was the most memorable thing that came to mind. Many of the cool scenes wouldn't have happened without Jang Won-young."
