“I, Evelyn Felice will abdicate as the Empress.”

“You’re giving up your fortune without my permission, and you’re happy at will.”

But a year later, like a coincidence, Fabian appeared again.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

Or will he succumb into a conspiracy lurking within the country's borders?
