During an episode of SBS's Running Man on April 20th, Ji Ye Eun showcased a slimmer face and more defined jawline, surprising the cast just one month after revealing her Ultherapy treatment. The show featured a "Running Market" auction, where members sold personal items requested by the staff.

The change in Ji Ye Eun's appearance was immediately noticed by the cast, with Yoo Jae Suk expressing concern about her weight loss, mentioning she woke up hungry on the previous day. HaHa and Yang Se Chan also showed worry, noting how tired she seemed and that she lost too much weight.

Although Ji Ye Eun joked about her new look, Ji Suk Jin humorously stated that she did not resemble a celebrity. The cast playfully lamented the disappearance of her double chin, likening it to a significant loss for a food enthusiast like her.

Yoo Jae Suk remarked on the potential change in her personality with the weight loss, while HaHa and others comically mourned the loss of her previous image. Despite the teasing, Ji Ye Eun confidently stated that she loved her new appearance when asked by Choi Daniel.
