The man who sued Park Eun Seok for defamation was on 'Penthouse' as an extra. Further, it was reported he also sued actor Kim Ho Young for sexual harassment back in 2019. 

On January 30th, media outlet YTN Star reported A, who sued Park Eun Seok, made an appearance on the third episode of the show as an extra for about 30 seconds. Additionally, it was reported that A was also the man who sued actor Kim Ho Young for sexual harassment back in 2019. The prosecution has removed the claim for insufficient evidence. Kim Ho Young then counter sued A over slander and defamation but his claim was also removed. Kim Ho Young appealed the case and thus A is currently going through a legal dispute. 

As previously reported, A has once again become the center of attention for suing Park Eun Seok from 'Penthouse'. An insider has confided, "Staff from 'Penthouse' thought A was just an actor. No one knew he was a casting director nor foreseen any of this legal dispute"
