Y/N is a mean girl who doesn't care about others even her brother yoongi who's also mean like her and loves to play this game called left 4 dead but what if..this game was not just a typical game but a cursed game?
And suddenly your brother and his friends appeared to the game as the character of the game.
But the only cure for the curse is someone to play the game and finish all the chapter of the game.
