There are several players in the "NAATO" reality show. During the competition, they are asked 10 difficult and sometimes funny questions, and the players must work together to find the correct answer. Among these players, one person has the role of "NATO". NATO is the one who already knows the answer to all the questions. Apart from the player who plays the role of NAATO, no one, even the presenter of the program, knows about the identity of this player.
