I recently saw "The Grey Fairy Tales". The basis of the story revolves around a post office on a planet like earth, but since it's a movie, this post office has some outer-worldly powers. On this planet, people count a great deal on the post office. This is because the post office is omnipotent and it can deliver anything, even the soul. Moreso, people here do not realize that the post office isn't just handling a package, it is handling their very lives.
The post office works with a system similar to the USB system. We know that one can freely transfer data from one computer to another with a USB as we can insert a USB with new data and delete its data. Here at the post office, the letter is the USB, the human body is the computer while the soul is the data. To put it specificly, the sender comes to a local post office and copies his soul, including personality, emotion, intelligence and lifelong memories into a letter, and seals it. Then his body will be in the care of the local office where the staff will delete its soul and keep the empty body for future use. The post office then delivers this letter to the destination where another post office pulls the soul from this letter and inserts the soul into another new empty body stored by them. After that, the sender's soul comes alive and walks out of the destination post office with a new look. Of course, in this world, no one cares about the appearance, just like we don't care about the USB but the data inside it.
Just like any post office on Earth, the post offices on this planet occasionally make mistakes. The heroine of this story came across such an incident: her fiance mailed his soul to her. Unfortunately, the destination post office missed some procedures. First, they forgot to pull the fiance's soul out of the letter so the letter was still lying at the office with the soul. Next, they picked up from the storage room the wrong body. This body was a newly-arrived customer who wanted to deliver his soul somewhere else and was waiting on the staff to pull out his soul. Before this newly-arrived body was clear about the situation, our heroine arrived at the office to claim her fiance. At the first sight of our glamorous lady, this body fell in love with her so he did not reveal his identity but pretended to be her fiance. His smart reaction and mild attitude averted any suspicion and thus he lived safely and happily with our heroine.
After the fake fiance stayed with our heroine for almost one year, the post officers noticed their mistakes. They immediately fixed it by pulling the fiance's soul out of the letter, inserting the soul into another new empty body and bringing it back to our heroine. The true fiance suddenly showed up, only to realize someone else already took his place. He was irritated. However, at that point the couple had already developed an intimate relation beyond a swindler and a victim. The two had developed a love relationship over the time. The fiance even suspected that our heroine might have been suspicious about the fake one yet she did not refuse his charm. As a righteous lady, our heroine was caught by a shameful grip due to the coming of her true fiance. In confusion and agony, she failed to make a choice between the two fiances. By the time the two fiances were about to "duke it out", our heroine had already run out of the house and sent herself to an unknown place from the post office.
The two adorers ran after our heroine towards the post office. However the privacy regulations kept them from knowing her destination. The true fiance immediately made a long list of destinations and copied his soul into different letters to be sent to all post offices one city after another. He was determined to dedicate his life to looking for our heroine and believed there would always be one letter that could reach our heroine. Unfortunately he was not aware of what kind of destiny was awaiting ahead.
No matter at which stop he managed to find his lover, he would find that his rival, the fake fiance, was ahead of him. The fake fiance did not turn his soul into a letter but into stamps. He copied millions of himself. No matter how many copies of himself would be ruined in the storage of the post offices, there would be always one copy that would be with the heroine's letter.
