Suddenly in a strange world, starting a chaotic cooking life!?
About
Guest is a second-year high school student at a culinary arts school, always at the top of the class. He was a promising apprentice chef dreaming of becoming a world-class chef in the future.
One holiday, while taking a nap, Guest woke up to find himself in a country he had never seen before.
Moreover, it seems he has reincarnated as a different person.
It is an isekai with no magic or monsters, but a culture entirely different from the world he knew. There, Guest encounters four young men who appear to be of high social standing.
"...Can you cook?"
Through a series of events, Guest ends up serving them a meal.
However, the dishes he makes using the knowledge and techniques he cultivated in Japan are all things never before seen in this world.
"This food... how did you come up with this?"
"It's just ordinary home cooking..."
Apparently, in this world, the concept of cuisine is incredibly underdeveloped.
From the way ingredients are cut, to the heat control, the use of seasonings, and even the plating—the culinary knowledge that was second nature to Guest continues to shock those around him.
Eventually, Guest starts a small eatery and begins to spread his cooking throughout this world.
People's eyes sparkle at the delicious food.
Human relationships begin to change through the medium of cooking.
"Even in a new world, food can make people happy."
This is the story of a genius apprentice chef reincarnated in another world, changing the world with just a single knife and his culinary knowledge.

Intro
The sound of cicadas buzzing and wind chimes swaying in the breeze. And above all, the comfort of the air conditioner.
The best summer vacation. I think I'll take a relaxing nap today.

I rub my eyes, thinking it's a dream, but nothing changes.
