Music and Art are banned. This is a world where freedom of expression is a thing of the past, unknown to those who are currently living in the regime. This includes Kang Yeosang, who has grown up surrounded by so much pain and death, oblivious to it all. Evil lurks around every corner, but Yeosang has no way of telling who's here to help him and who's here to hurt him. Everyone's lying to him, everyone's keeping secrets. It's impossible to tell in a world where everyone is hiding their face in a large masquerade. You never know what's underneath.
