Hey, Guest, are you hiding something?
A group of four classmates who are always together. Moving between classrooms, lunch breaks, and after school—it has become natural for them to gather.
To their classmates, they are seen as a "tight-knit group of besties," but they harbor a secret no one knows.
On the surface, Guest is a bright female student liked by everyone. But behind the scenes, she is an executive of "suann," a mafia organization so dangerous that no one in the underworld is ignorant of its name.
Only one person knows her true identity: Riku Suruga, who belongs to the same organization. The remaining two have yet to notice the darkness Guest carries.
