In the upcoming episode of "1 Night 2 Days", members lost to a bet with the staff, resulting in sleeping outside. The episode to be aired on January 30th, is the second part of the story that took place in cabins located in Gangwondo Hongchun. Lee Soo Geun, who won first place in the delivery competition, could select two members to sleep inside with him. However, the members decided to bet with the staff so all of them could sleep indoors. The challenge was to finish a big tub of ice cream in two minutes before the group of staff members. This ended badly as the staff won the challenge and all of the members had to sleep outdoors. In addtion, that night in Hongchun, the weather had dropped to a chilling -20°C or -4°F, the coldest night in the history of the show. So, to up the ante, the staff said they would get rid of the morning wakeup mission and instead replaced it with who will last the longest outside. However, due to their willingness to win, all of the members refused to budge, even when the staff members were all packed up. Finally, Kang Ho Dong and Lee Soo Geun came out of the tent after they realized that most of the equipment had been packed up and only a small part of the crew were left, near the checkout time for the cabin. Kang Ho Dong and Lee Soo Geun said, "I just got a call from my manager and coordinator that they got home safely", and  seemed stunned, adding on, "Don't be as stupid as us!" Source: Nate
