can a person did not have a back story

No. Every person has a back story, whether it's known or not. A back story includes things like where a person grew up, their family situation, and experiences that have shaped them. Even if someone seems like a mystery, there are still events and circumstances in their past that contribute to who they are today.

No. It just suddenly appeared without any back story at all. It seems to be just a simple element in the story with no past or origin to speak of.

I don't think so. A person's back story is what makes them unique. It includes all the things they've been through, like their education, first love, first job.

It was possible for the lost person to come back, but the exact situation depended on various factors. If it's a friend you've lost contact with, you can take the initiative to ask them out for dinner and chat to reestablish contact. However, if you lost someone who loved you, it might be even more difficult to get them back. Modern society had developed communication, and it was easy for people to keep in touch. If you lost someone, it might mean that you hurt their heart. In addition, if an item was lost, the possibility of recovering it also depended on the specific situation. If the bank card was taken away, they could report it to the police to protect their rights and interests. If the phone was stolen, the possibility of recovery could be increased by calling the police, reporting the loss, and using the lost mode of the phone. However, if the item had been abandoned or sold, the chances of finding it were slim. In short, whether the lost person or item could be returned depended on the specific situation and the measures taken.
