The Emperors Secret Heir

20 years ago, the Emperor was ambushed, and the Empress took an arrow for him, losing her memory and wandering among the commoners. 20 years later, Crown Prince Julian Shane topped the imperial exam but was framed by his wife Sharon Brown and foster brother Fabian Luke, leading to his exile. 5 years later, he refused the throne to stay with his wife and daughter, but they despised him, took in a traitor into their family, and had even harmed his mother. He then returned to the palace, ascended the throne, and punished them all.
