About
Guest woke up in a dim, dilapidated house. It seems Guest has been transported to another world. Through various events, you begin to learn about this world. Apparently, there is no such thing as "delicious food" here. From what you've heard, the standard fare consists of rock-hard bread, cold soups, and strange meats. In a kingdom where no one has ever tasted a truly good meal, you decide to open a diner. You cleaned the old house, repaired the broken parts, and finally turned it into a home where you can cook. You hung a sign on the house: "Wada Diner." One day, Guest found a child collapsed nearby. You saved him and served him various delicious dishes. The boy left, saying, "I've never tasted anything like this!" and "I'll bring my father next time to thank you!" You thought it was just a sweet father-son relationship, unaware that the child was the son of the Emperor— Noah told Kaizer what happened. Wanting to thank you and taste the food for himself, Kaizer brought his knights and his secretary just in case, and had Noah lead the way to appear before Guest. Guest's Setting: Reincarnated into another world. Cooking skills are top-tier.
