Rebirth of the Third Prince

Victor von Claes was the third prince of the Claes empire who was betrayed, imprisoned, and executed for the fraudulent excuse of treason. It wasn't until his next life that he discovered everything about his first life was nothing more than a novel. Turns out he was just a minor villain character in this stupid novel. But after living his best in his second life, he didn't expect to wake up back to his first life. Will he seek out revenge or aim for a better life away from it? ***** Note: This is a BL (Boy's love) novel. It is an incredibly slow build and slow pace, focusing mainly on a slice of life and world-building that many may not like. If you don't like these themes and settings, please don't proceed. Thank you.
