I am the main protagonist of a shitty novel

In this captivating story, our main character tragically meets his demise, only to find himself reincarnated in a novel that he despises. To make matters worse, he's been reborn as the protagonist, accompanied by an unexpected and rather questionable companion - a plot system in the form of a loli. As he navigates his new world, he quickly realizes that he's now surrounded by an odd harem of individuals, adding yet another layer of complexity to his already difficult situation. What's more, his foes in this realm are none other than the powerful beings known as the "Gods," presenting him with a formidable challenge that will test his skills, intelligence, and strength in ways he never thought possible.
