How Do I Run a Magic Tavern with Amnesia?

Good news: I painlessly inherited a magical tavern. Bad news: I have lost my memory, I have no literacy, no common sense, and I don't even know the name of this place in the middle of nowhere. The system said: You have to open a good pub and make every customer happy. I said: Can I survive first? Later, my tavern hired a strange staff. An old woman of unknown origin. A mentally disturbed giant. A pair of orc mother and daughter who hide their identities. A cursed low-level messenger. … In short, a group of old, weak, sick and disabled people. The guests who come and go each have their own tragic lives: a fugitive mercenary, an unknown witch, a wandering dwarf, a real and fake daughter, a singer who lost his voice... With my cleverness and wit, I discovered the stories of these people one by one. After all, there is no such thing as a job. Just when I was about to start a happy melon-eating life, trouble came unexpectedly. The Reinaka Holy Land, which monopolizes potions, sent a messenger with his nostrils pointed in the sky: "Either stop selling it or hand over the formula." I'm looking forward to it, ready to bear it hard—— Then, my group of old, weak, sick and disabled employees and regular customers stood in front of me one after another. The giant raised his axe. The orc mother and daughter showed their sharp claws. The Rune Master took out a powerful alchemical cannon. The most amazing thing is that the real and fake daughters directly joined forces and overturned Reinaka's table. Aren't they a bunch of poor people? Why have you all become bosses?
