Every guest who enters "Black Rose" has an unhappy memory, and the owner Rose is the one who can help them solve it. She seemed to have an extraordinary power, like an angel who could bring the dead back to life to help those people. But she also wants to ask for reward, but the reward she wants is very strange, which is the unhappy memories of those unhappy people. It sounds strange, even incredible. But please don't doubt it, since she can make those people forget their unhappy memories, why can't she ask for those memories as reward? It's not against the law to take things that others don't want, and those customers also signed a contract, one thing for another. It's a very reasonable transaction, but I don't know if it's fair or not. Seeing this, has anyone begun to wonder, who is this shop owner? What does she do by opening this store? Why does she want those people's memories? Who knows, I don't know very well. If you have the "detective" spirit to get to the bottom of it, then please follow me and let us explore those secrets together, okay?
