얼어붙은 플레이어의 귀환

Seo Junho and his companions gave their lives to bring down the Frost Queen, believing they were handing Earth back its peace. Junho instead spends twenty-five years frozen solid, and when he thaws he finds a world that moved on without him: nine new floors have opened in his absence and only one of them has been cleared. As the one player who still holds the key to the rest, he steps back into the game to clear the floors and thaw his friends.
