Kim Jong-kook wrongly identified Lee Se-hyun for Son Heung-min during a broadcast of the show Running Man. The amusing slip happened because Lee Se-hyun and Son Heung-min share remarkably similar visual styles. Kim Jong-kook could not hide his surprise at their matching appearances while filming.
Ji Ye-eun also took part on the same show and became quite emotional. She revealed to viewers that her first blue-chip stock fell by 47%. Ji Ye-eun also mentioned that Kim Jong-kook had previously warned her not to invest. She pointed out that Kim Jong-kook predicted the drop before she bought into the stock.
