With the development of the times, in addition to technology, there is also the growing sense of dissatisfaction in people's hearts. This is a kind of emptiness hidden in the heart, which includes the pressure of people's work and life. At this time, a company called "Beautiful Dream" was established. It claimed that it could eliminate stress without any side effects, and charged fees according to the amount of stress. People went to try it skeptically, only to find out it was true. Soon, "Sweet Dream" became a place to release people's stress, and the company was constantly praised by the upper class. However, people there gave the company another name - "Dream Eater".
