When I opened my eyes, I found myself in the Joseon Dynasty, transmigrated into the body of Grand Prince Yangnyeong—the eldest son of King Taejong.

According to history, my fate is to be deposed as the Crown Prince, and the throne will go to my younger brother Chungnyeong, who will eventually become the legendary King Sejong the Great.

However, I am a transmigrator! Armed with knowledge from the future, I am going to preemptively build the glorious Joseon that Sejong was supposed to create!

“I’m sorry, Chungnyeong. But there is no King Sejong in my Joseon.”
