Daisuke Hagaromo is a 19-year-old who is completely bored out of life. His bad decisions had gotten him to the worst place he could have imagined when he was younger, and every day of his life felt miserable. He intends to commit suicide in a quick and painless manner, jumping off the roof of the 100-story building with his eyes closed and succumbing to his miserable fate. He dies successfully, but awakens to find himself floating in a void, greeted by a divinely inspired digital system. In exchange for his eternal submission to the system's conditions, the system offers him a chance at a new and more fulfilling life. Daisuke, against his better judgment, accepts the offer and is transported to another dimension of reality. He would be assigned difficult missions and put through impossible trials there, which would later be revealed to be a path to greater life and immortality. ******* This is a system novel set in medieval times with mythical characters and situations. It is NOT a harem, and there are very few sexually explicit scenes. My world building and character development aren't the best, but they will improve with time. I hope you enjoy it, and if you do, please consider supporting, reviewing, commenting, and following. Have a good time!

Ethan Black died a forgotten man. After sacrificing everything — his dreams, savings, and dignity — for the woman he loved and her ruthless family, they discarded him like trash at her engagement party to a richer man. One final "favour" later, bullets ended his pain… or so he thought. Reborn as Vesper Kane, the tyrannical villain of the novel his late father gifted him, Ethan wakes up with a System and a death sentence: 365 days until his fated execution. With a survival probability of just 0.01%, the entire world — the Hero, Heroines, King, and even his own family — wants him dead. The story itself fights to restore the original tragic ending. Armed with future knowledge and a sharp, sarcastic System, Ethan must rewrite destiny itself. Every deviation makes him stronger… but the world pushes back harder. From hunted fugitive to shadow emperor, this is the story of a discarded man who refuses to die on schedule. The countdown has begun. Will he break the system… or will the system break him?
