Kim Jong-kook briefly mistook Lee Se-hyun for Son Heung-min in a recent episode of the show Running Man. The funny confusion happened because Lee Se-hyun and Son Heung-min display strikingly similar visual styles. Kim Jong-kook reacted with amusement to their matching appearances during the recording.
Ji Ye-eun also took part on the same show and became visibly upset. She explained that her first blue-chip stock fell by 47%. Ji Ye-eun also mentioned that Kim Jong-kook had cautioned her against the purchase. She pointed out that Kim Jong-kook predicted the drop before she bought into the stock.
