Villain's Refund System: The Protagonist's Harem Is Mine

Damien died at his desk after finishing a 2,000-chapter webnovel and woke inside it as the trash villain everyone loved to hate. In the original story, Damien loses his fiancée, inheritance, reputation, and life so Lucas Arden, the golden protagonist, can rise. Now Damien has seventy-two hours before the gala where his humiliation is supposed to begin, while his final death is already marked at Fatality: 100%. Then the Refund System binds to him. Every time he survives a genuine fated death flag, every reward attached to it multiplies by ten. Armed with foreknowledge that decays whenever he changes the plot, Damien begins hijacking Lucas’s scripted victories, turning assassins and Corrections into jackpots... pulling people out of roles designed to feed the hero’s legend. But the more characters choose their own paths, including, sometimes, Damien, the harder the Script fights to force them back. To survive the ending, Damien must become something far more dangerous than the villain the story wrote him to be. — Description from novelcodex.org
