Kim Sae Ron's family's lawyer, Bu Ji Seok, is facing public backlash after footage emerged of him dancing and yelling in a Gangnam nightclub while video from the actress's press conference played on large screens.

The footage was released by YouTuber Lee Jin Ho, who alleged in a video uploaded over the weekend that Bu was seen at the club on May 11, the same day footage from Kim Sae Ron's recent press conference was projected throughout the venue.

The lawyer had appeared at the press event alongside Garo Sero Research Institute members Kim Se Ui and Kwon Young Chan to address the controversy surrounding Kim's relationship with actor Kim Soo Hyun.

"I am at a loss for words about this," Lee said in the video. "I wonder if this is all really to restore Kim Sae Ron's image."

The clip, which shows Bu Ji Seok dancing among clubbers while the press conference footage played in the background, went viral, prompting strong reactions from South Korean netizens.

"This is not right... the gods will punish them... and to the bereaved family... if you have eyes and ears, you should see how your daughter is being consumed at the Gangnam club," one netizen wrote.

"Although going to the club is a personal preference, why are you playing the press conference video at the club? Do you think the deceased was wronged? This type of mindset is something I cannot understand," another user commented.

Others were more blunt in their condemnation.

"The club video is shocking. So shocking. I guess pigs are doing business at the club," one comment read. "Bless the person who reported this video and showed us the real face of these pigs."

The incident comes in the midst of ongoing public scrutiny following the Garo Sero Research Institute's claims about Kim Sae Ron and Kim Soo Hyun.

Not long after the press conference, Kim Soo Hyun released a statement refuting the accusations and called the claims "complete lies."

The full video released by Lee Jin Ho remains available online, continuing to draw attention as the controversy unfolds.
