Once upon a time, in a faraway land called North Korea, there was a game called "The Lights Out Game." It was a very dangerous game where players had to eliminate each other to win. One of the players was a brave and stoic girl named Sae-byeok. She was 5'9" tall and had a strong spirit.

In the game, the players had to turn off the lights and find their opponents in the dark. Sae-byeok was very skilled at hiding and sneaking up on others. She knew that to survive, she had to be smart and quick, until she seen some girl getting attacked by some guy.
