Fantasy

As a successful author, Max was used to hate comments but he never expected that his decision to kill an important character would result in his death.
    Apparently, the Goddess and her brother used to read his novels and were both a big fan of his works. Sadly, the brother didn't like his decision and killed him.
    As compensation, the goddess decided to send Max in his own novel as the protagonist and complete the story without letting any of the main characters die.
    Max had no problem with that, so he accepted it and asked for something else too.
    “Can I court you?”
    Now, he has the Goddess accompanying him as the Ultimate Leveling System. Not only that, his system also rewards if he saved the favourite characters of his novel. What could be better than this life?
    [You have Killed the Giant Behemoth Dragon, granted 200000 EXP.]
    [You have saved the side character, Charlotte Sinclair, granted the fortune worth Corelhelm Kingdom.]
    Watch as how the author makes the harem of his favourite characters while leveling Endlessly.
