4x165 - 2 Days and 1 Night

Location: Taean, South Chungcheong For this week's trip, the members are given a chance to bond with one another by going on a retreat to Taean. They're allowed to use the items they brought in their suitcases. On top of that, they get to use the items from the show's prop truck. However, if they fail in the missions, they will have to give up on their items and survive with only the remaining ones.
