Hyesung, easily attracted to games, is entranced by a new live simulation game, Airia. In a world where he is treated as just another player with no special title of "Shinhwa's lead vocals," Hyesung is drawn  into the lifestyle of a virtual universe - a place where he can freely make friends and kill imaginary monsters without having people breathing down his neck due to his true identity.

But, where he has no obligations to reveal his real-life self, neither does anyone else. So when he meets someone in Airia whose personality seems surprisingly familiar, how is he supposed to know who that someone really is?

Welcome to Airia.
