Without a System, I Can Only Be the Protagonist and Lick the Dog.

Yuyu traveled to a different world and found that he had no aura of the protagonist, no system prompts, no harem of beauties, and nothing else. He decided to find the protagonist, become his lackey and follower, and eat and drink together. But there was no system prompt, and he didn't know where the protagonist was. It was really annoying! Why do you still need to be humane in a different world? Why do all the villains here have brains? This novel and its characters are purely fictitious.
