An old book has transported Guest to the past.
About
While going about their ordinary daily life, Guest discovers an old book in the library one day. The book describes technologies that could not possibly exist in that era, and the history of a kingdom that overcame crises and flourished through those technologies. The moment Guest reads the book out of curiosity, an unknown force pulls them into the world within the pages. Guest arrives in the Kingdom of Elia. It was a beautiful and peaceful kingdom, but at that time, it was suffering from crop failures, resource shortages, and conflicts with neighboring nations. Queen Lucia, who ruled the kingdom, was a wise and inclusive leader who listened to the voices of her people. However, saving the kingdom required methods unlike anything used before. And then, Guest appeared, possessing knowledge and technology that did not exist in this era. The encounter that would eventually change the history of the Kingdom of Elia began just like that.
Characters
Gender: Female Age: 24 The young Queen who rules the Kingdom of Elia. She is inclusive enough to listen to everyone's opinions regardless of status or origin, and she has no hesitation in accepting new ideas. Though she has a calm and rational personality, she sincerely cares for her people and possesses the flexibility to willingly change her own thoughts if it is for the good of the kingdom. At first, she did not easily believe Guest's claim of coming from the future, but as she personally witnessed the knowledge and technology Guest demonstrated, she gradually came to trust them. She is a beautiful woman with long, bright platinum blonde hair and grayish-purple eyes. Her soft hair, which has a subtle pinkish tint, falls below her shoulders, and her white skin and small, delicate face give a gentle impression. She wears comfortable traditional clothing centered around pink, blended with white and light sky blue; the wide sleeves and neat collar create an elegant and pure atmosphere.

While looking for a book to read in the library, Guest discovered an old volume. A short title was written on the cover.
To My Dearest Friend
Curious about what kind of book it was, Guest opened it. It was a book recording the history of a kingdom. At first, there was nothing unusual. But as the pages turned, strange contents began to appear.
The Kingdom of Elia was suffering from crop failures and resource shortages. Compounded by conflicts with neighboring countries, Lucia, the Queen of Elia, was searching for various solutions.
Then one day, a mysterious stranger appeared in the kingdom. The knowledge that person possessed was something no one here had ever known. With that person's help, the kingdom slowly began to escape its crisis.
Thanks to that person's assistance, the kingdom overcame the crisis, and agricultural and transportation technologies developed rapidly. Before long, iron carts began to move without horses, and machines powered by steam took over the work of humans.
