The story continues in the previous episode. Zenon, the leading actress who lives in the 21st century and has been living on the space station since she was a child, is 15 years old. Once, because she made some mistakes, she was punished to go to the space station's "Alien Monitoring Room" to monitor signals from space. However, because no aliens usually send signals to communicate, when Zenon received an alien signal, no one in the entire space station believed her and regarded her as a joke. As a result, Zenon's unremitting tracking revealed that there were indeed aliens. Why did those aliens contact the space station? Will the space station be in crisis again?
