According to the Japanese brief introduction, Prince Guangping was not cursed to death (but Queen An Zi died very early at the age of 38). Prince Guangping suffered from mental illness since childhood. After Nariakira's death, Prince Guangping succeeded to the throne (later "Cold Spring Emperor"). After decades of madness, he was manipulated into a puppet by the Fujiwara family and almost abolished. After two years as emperor, he stepped down.
