I Used to Be an NPC

I used to be an NPC. After inexplicably awakening, I started a miserable life working for the God of Creation. The part-time job is to travel between different worlds as an NPC. The specific part-time job content is that I cheer for the protagonist to save the world, give money to the protagonist to start a business, check the pulse of the protagonist during palace battles, and make trouble for the protagonist in sadomasochism. But this kind of life is getting a bit annoying after such a long time, so the God of Creation has waved his hand, and you will be the protagonist this time! The content of the story is - you were once an NPC.
