I Just Want to Be a Quiet Cook

[More to come. The title, blurb, and opening are all due for revision...] Kitagawa Gen opened a restaurant. The restaurant was in a remote spot, surrounded by either wild beasts or poor people. Dreaming of escaping the troubles of the world and quietly becoming a good chef, Kitagawa Gen was very pleased with the location and decided to sit tight and wait for death. But could someone explain to him: Why did all sorts of strange customers keep showing up at his restaurant? And when did his restaurant become a counseling center? An older brother who had a serious falling-out with his younger brother and looked completely unreliable. A trio who were so broke they could barely pay, and whose occasional sources of money were suspicious. A child who went looking for their unreliable father at such a young age. A gentle, dependable big brother with a box on his back, the polar opposite of a certain customer. Where did all these people come from? Most importantly, why did so many people think they could eat and run at his restaurant? 1. Mainly One Piece. Characters from other series only show up as customers, and don't feature much. 2. Out-of-character writing is inevitable. I've only watched the anime, not read the official novels, so please overlook any mistakes. 3. A brainless fluff story with no logic. 4. The protagonist is invincible, a total Gary Stu. 5. Pairing: Ace. Theme: Food is the people's first necessity
