[Will you join the game?] Giyoung's suddenly thrown into a game of life and death. Not only that, but he's also the player with the lowest stats. Still, he's got one skill on his side: the ability to read other players' status! He finds the opportunity of his life when he discovers that Hyunsung is a returner to this world. Now all Giyoung has to do is stick next to Hyunsung and game his way out of this tutorial.
