I opened my eyes to find myself in the Joseon Dynasty, reborn as Prince Yangnyeong, the eldest son of King Taejong. Destined to be deposed as crown prince, the throne was meant for my younger brother Chungnyeong, who would later become King Sejong. But I am a transmigrator. Using my future knowledge, I will build the Joseon that Sejong was supposed to create—first!
"I'm sorry, Chungnyeong. There is no Sejong in my Joseon."
