Kim Hae-won has lost complete faith in humanity. After surviving the games in 2013 at just eighteen years old, Il-nam offers her the opportunity of a lifetime: become the hostess for the games. For eleven years, she and the Frontman, Hwang In-ho, operate the games side-by-side. That is until Seong Gi-hun, a disgruntled previous winner, wishes to come back to the game. Determined to tear him apart, Hae-won infiltrates the game once more, except she gets more than she bargained for; A reunion with the only boy she'd ever loved. Now Hae-won's morals are put into question and she has to decide whose team she's on. The man rebelling against all she believes? The man controlling the games behind the scenes? Or the boy she abandoned eleven years ago?
