I Regressed for Revenge

Myriad was a king who was betrayed and stabbed by his childhood friend. After getting a second chance at regressing by a so-called angel in disguise, he vowed to only pursue his own Interest which is to claim the title of king for himself, marry the woman he loved trampling the kingdom of Traxdart for fun, creating an empire and making sure the backstabbers in his previous life get what they deserve.

He appeared in his body ten years ago when he was 19. A day before he became king!

...

Afterall, that's what I'm living for. It's a life for revenge!
