Transmigrating into a Mob Character to Rehabilitate the Villain Plan

In short, this is the tragic tale of a saint-like man who transmigrated into a web novel as a mob character and wanted to rehabilitate the villain, only to realize in the end, he became more and more villainous. The ludicrous story: Unable to bear hurting the villain he helped raise, but when it came to compensating with his own body, the unfortunate, straight male reader figured he’d better escape… … Many years later, the same unfortunate saint rubbed his neck, asking, “This is a dog collar you put on me, isn’t it?” The handsome villainous boss gave a glance with his elegant, almond-shaped eyes, and then replied with a devious, charming smile, “That’s to prevent you from running away again.” “If I stay put, will you refrain from destroying the world?” (Source: Novel Updates)
