Kim Jong-kook briefly mistook Lee Se-hyun for Son Heung-min during a broadcast of the show Running Man. The funny confusion happened because Lee Se-hyun and Son Heung-min share remarkably similar visual styles. Kim Jong-kook reacted with amusement to their matching appearances while filming.
Ji Ye-eun also joined the cast on the same show and became visibly upset. She explained that her first blue-chip stock fell by 47%. Ji Ye-eun further stated that Kim Jong-kook had previously warned her not to invest. She noted that Kim Jong-kook had accurately predicted before she acquired the stock.
