Song Joong Ki is returning to his Running Man family! The actor and former Running Man cast member will be a surprise guest on next week's episode.

Next week's episode is jam-packed with guests, as Song Joong Ki will be joined by Jo In SungIm Ju HwanHaha's wife Byul, Kim So Hyun (the musical actress, not the teenager) and her husband Son Jun Ho. The guests will form two teams to compete in the "Love and War Race."

What makes me love this lineup even more is the fact that BFFs Lee Kwang Soo, Song Joong Ki, and Jo In Sung left together on a friend vacation not too long after they filmed this episode. The bromance — it is real!

You can see Song Joong Ki's triumphant return to Running Man next Monday, June 15. In the meantime, check out the latest episode of Running Man, featuring the guys of BIBGANG:
