The first episode of season three of "1 Night 2 Days," which unveiled on December 1, 2013, has added new faces in addition to its classic concept, transforming the third season as a hybrid entertainment program.

On the first episode of KBS 2TV "Happy Sunday - 1 Night 2 Days," which aired on December 1, 2013, the new members introduced themselves and travelled for the first time. On this episode, the previous members, actors Cha Tae Hyun and Kim Jong Min, attacked the four new face members, actor Kim Joo Hyuk, comedian Kim Joon Ho, singers Defconn, and Jung Joon Young, and introduced the sleepy new members into a world of wild lives. This was actor Kim Joo Hyuk's first appearance in an entertainment program since his debut. The other three were beginners in entertainment programs, only experienced in them a couple of times. Although their lack of experience in entertainment programs have raised concerns before the start of the season, they appealed with unique charms in the first episode aired today.

The first trip on this day's episode was very similar in format with the previous trips in previous seasons of "1 Night 2 Days."
