In a peaceful neighborhood stands a house topped with a crimson roof. Nearly two decades ago, a tragic event unfolded within its walls - the brutal murder of the parents by their own daughter, Aota Ayako, and her partner, Obuchi Hideyuki. This heinous crime captured global attention, especially when Hideyuki confessed to past acts of assaulting young girls in his book "A Premature Autobiography". Throughout the trial, it was revealed that Ayako had been manipulated by Hideyuki into committing the crime, leading to his death sentence and her life imprisonment. Some time later, a new author named Ogura Sana proposed a novel idea to Hashimoto Ryo, an editor at Todoroki Shobo, based on this tragic incident. As they delved into interviews with key figures involved, such as Obuchi Reiko - who married Hideyuki while in prison - and his former mistress and skilled editor, Ichikawa Seiko, they found themselves entangled in a web of dark emotions. Little did they know, a shocking revelation awaited them, hidden from the world's knowledge.
