Running Man' Kim Jong Kook suspected Song Ji Hyo and Kim Jae Young were secret couples in solo units.
On the 31st, SBS "Good Sunday - Running Man" was a solo match race.
On this day, "Finding Secret Couples in Solo Unit" was given as a mission; Kim Jong-kook, Song Ji-hyo and Jae-young Kim were tied up in a team. On the move, Song Ji-hyo took Jae-young Kim's hand, while Kim Jong-guk suspected Song Ji-hyo and Jae-young Kim. Song Ji-hyo explained, "I caught him while driving him as a secret couple."
Kim Jong Kook said, "It is a style that makes Jae Young look at the same style. "If we get a mission, we pretend to be in bad shape," Song said, pretending to be sick and Jae-young Kim pretending to be in bad shape. So Song Ji-hyo said that it was because Kim Jong-guk was driving.
Song Ji-hyo's explanation did not raise doubts about the two, and Song Ji-hyo embarrassed Kim Jong-guk by saying, "If we are not a couple, my brother is jealous of me."
Meanwhile, Running Man' is broadcast every Sunday at 5 pm.
