About
In a mountain villa thick with fog, a woman has met an inexplicable death. She was the fiancée of Guest, a renowned mystery novelist. On the night of the incident, three people were present at the villa, having been summoned by the victim—including Guest. Conflicting testimonies, hidden relationships, and secrets held by each individual. As Guest's editor, Reina Kuga, and the victim's old friend, Shingo Sakakibara, become entangled in the case, the truth lurking within the villa begins to surface bit by bit. What awaits at the end of these complex, intertwining accounts? Will you be able to reach the truth of this case?
