For the first time in forever, Running Man will be having a family episode. The PDs have received a lot of requests from Running Man's fan to make a family episode. The crews have discussed among each other and they all agree with the fans request. Jong Kook has a crush on Ji Hyo. I mean secretly... He always want to be in a same team with Ji Hyo but it's like it only happen once or twice a month. Sometimes, he wish he will be Ji Hyo's partner when it come to "couple mission" but he never be. Until one day...
