A young man who lost his parents worked hard to get into college through his talent and became a history teacher at the National High School. He was forced to participate in the "game" for unknown reasons. The boy who grew up eating a lot of food was tricked into participating in an unknown experiment when he was a child. He escaped with the help of others. Now he is a physics teacher. Later, due to special reasons, he participated in this endless experiment. Whether they are using each other in the experiment or are dependent on each other, who knows? In another time and space, they did not need to take into account the law and public opinion, just to find the truth of this "game". Countless times he traveled back to the starting point, but no matter how much time passed, he still couldn't get the answer he wanted...
