I Was Caught Up In a Hero Summoning, but That World Is at Peace

Story:

It was as if I had fallen into some kind of trap, which is similar, as they say in the books, to: “calling a hero” – suddenly appearing in a different place. Not a problem though! I'm not a hero! He turned out to be a completely different person… And I was already afraid that I would be thrown into the maelstrom of battles and bloodshed, but no. You will probably have questions about this world. Is there a Demon Lord here? Alas, he was defeated a thousand years ago. So, why a Hero? And he is just a sent actor from another world. And what about the nobles? They kindly take care of us. Demons… they must be evil? No, not at all. They have good relationships with people. Even families. Well, then maybe the war is raging? Oh, God forbid, the last one was like eight hundred years ago. Maybe then monsters bother you? Don't worry, the guild and the knightly order have taken care of them. Will I be able to return home safely? No problem. And what am I planning to do after I have been called? I will enjoy life in another world as much as I want. I will go on a short trip, making a cultural exchange and sightseeing, and then I will definitely visit the festival, which is held only once every ten years! And after… I'll be back home safely.
