On the March 9 episode of 'Law of the Jungle,' SF9's Rowoon and Kim Byung Man helped each other out as they began their survival in Patagonia. The two began by building a house and heater together, understanding each other so well, there was no need for words!

Moments of bonding also sparked hard work and inspiration. Like a son wanting to impress his father, Rowoon gathered new tools and occasionally spoke to himself: "This will make him feel proud of me, right?" 

As Rowoon's efforts came in handy, Kim Byung Man relied on the idol to quickly establish their surroundings.
