Memory Reseller

There is a group of people in this world who claim to be memory resellers. They walk among the crowd, buy memory cores that some people no longer need, and then resell them to people who need them. Removing the core of a memory requires three conditions: an item that stores the memory, a personal account of the original owner of the memory, and physical contact with the original owner. After the core of memory is taken away, you can still remember that past event, but you have lost your personal emotions. Looking back, it's like watching an old movie. As for the memory reseller - the transfer medium for each resold memory, as different memories taste the ups and downs of the world, what kind of legendary experience will this group of young people with supernatural powers have?
