Do-un reveals the behind-the-scenes story of ‘Daedeungwae’ himself… Got completely beaten up by the snow mountain climb lol

It's so funny that at the 'Daedungwae' press conference, Dowoon said he felt like he'd been "scammed into a job" after finding out about the snow mountain climbing concept lol.
I am curious about the process of how Do-un, who is usually far removed from hiking, ended up actually climbing a snowy mountain.
I definitely have to watch from the first episode to see how they performed on the show!
