MBC Music's Seventeen One Fine Day is a reality show that has previously features SHINee, VIXX, B1A4, Amber, AOA, Girl's Day and GFriend among other popular idol groups. Seventeen surprised the production team, who assumed the group wouldn't be able to do anything and be confused when left strandend on an island, by fending for themselves just fine, from preparing a 39-person meal with various side dishes, even kimchi, to filleting raw fish.
