I met the male lead in prison.

In a world where villains are crafted, not born, Vyan's life takes a detour from dull to downright dramatic faster than he can say “abracadabra.”Meet Vyan, the most ordinary knight in the realm, with all the magical prowess of a damp sock. Loyalty? He's got it in spades. Betrayal? Well, that's the surprise twist in his not-so-fairy-tale life.Framed and forsaken, Vyan is left with nothing but a grudge and some pretty gnarly scars, courtesy of his once-master, Iyana. Oh, did he mention she is the daughter of a marquess and the object of his unrequited affection? Talk about adding insult to injury.Just when he is ready to unleash his inner berserker, a butler comes along with news that makes his hair stand on end: Vyan is the last heir of the Grand Duke's mage dynasty!With power crackling at his fingertips and more mana than he can shake a wand at, Vyan is ready to show the world what happens when you underestimate the underdog. Will Vyan rise from the ashes like a phoenix, or will he crash and burn like a fire-breathing chicken? There's only one way to find out.

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. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
