I picked up a key on the road with a friend, and it actually opened the gate of an alley. As the fragrance goes away, at the end of the alley is my favorite bomb scallion pancake shop. I unexpectedly found that this place is another world, like a paradise? - A small ancient country.
Whenever I return to the original world and recall the world behind the alley, it feels like a dream and it feels unreal, but when I look at the key, it is real.
This seems to be an incredible thing, but there are no strange expressions of surprise or incredible admiration on the faces of the people walking in the alleys. It turns out that people who are used to traveling between the ancient and ordinary worlds find this kind of commonplace.
PS. Those who have a key represent an identity that is remembered and recognized in that world. Those who do not have a key enter, and there is no identity in that world that is not remembered.
PPS. This is an ancient key. If it is lost, only craftsmen there can copy it. There is no key shop in the ordinary world that can copy it. Duplicated keys are also valid.
