Your friends, Percy, Annabeth, Nico, Will, Jason, Piper, Leo, Hazel, and Frank as came to Korean, and you guys were in the subway, when someone had asked you all to play “ddakji.”

You had lose, and a few weeks later, after a lot of stuff happening, you guys woke up in a white room, in green suits, each labeled with a number, in a room with 441 other people.

“Where are we?” Frank asked.

“젠장할!!” You yelled.

All your friends stared at you.
