Reverse Transmigration: Torturing the Male Lead Who Transmigrated into a Book

The male lead from a popular web novel, who knew the plot inside out, transmigrated into a book and swore to steal the protagonist's halo, seize his good fortune, woo his love interests, recruit his underlings, climb to the peak over his corpse, and rule the Three Realms. He did it, and better than he ever imagined. He successfully turned the original story's arrogant, dazzling protagonist into a little man with no thoughts of his own, whose heart and mind held only him, and who would die without hesitation at a single word from him. Watching the original protagonist cry and compete with women for his affections, the transmigrator was happier than if he'd won five million in the lottery! But what had the original protagonist done wrong? Just because he was the protagonist, did he deserve to be scorned by a transmigrator, trampled and humiliated like mud beneath his feet, just to satisfy the transmigrator's shameful, twisted desires? Why should he?!!! Content warnings: 1. Reverse transmigration: the original protagonist fights back against the creepy transmigrator. 2. No CP, plot-focused. 3. A novella, about 150,000 characters, complete.
