The Mob Villain's Second Run I Refuse to Lose to the Hero Again.

Cassian Rosenfeld was born as the eldest son of one of the most powerful noble houses in the empire. Arrogant, spoiled, and protected by his family name, he believed the world would always bend beneath his feet. Until one mistake destroyed everything. After cruelly humiliating a servant-born girl at the Royal Academy, Cassian challenged Leo Brightvale, the shining young hero loved by everyone. The duel ended in disaster. Cassian was defeated, condemned, stripped of his position, abandoned by his family, and left to rot in the shadow of the world he once looked down upon. He died alone. But death was not the end. Trapped in darkness, Cassian was forced to watch the life of the hero who ruined him. He watched Leo grow stronger, save kingdoms, gain allies, win love, and reach a perfect ending. And only then did Cassian learn the truth: Leo Brightvale was not simply a blessed genius. He was a soul from another world. A man who had already lived once before. Cassian was never the true villain. He was only the first obstacle. A stepping stone. A forgotten stain on the opening page of someone else’s legend. But as his soul sank into the endless dark, one thought refused to die. If I had one more chance… This time, Cassian Rosenfeld will not waste his life. This time, he will not chase position, pride, or empty noble arrogance. This time, power will come first. And if fate has written him as an insignificant villain, then he will tear that fate apart with his own hands.
