An APP called "Hello, Tomorrow" that cannot be uninstalled is automatically installed on the protagonist's mobile phone. It will push an accurate preview about the protagonist's "tomorrow" on time at 3:33 every morning. At first it was just trivial things ("You will receive a sales call at 9 a. M. Tomorrow"), but soon the content of the trailer began to become weird and terrifying, until it pointed to death. The protagonist finds himself trapped in a desperate loop: no matter how hard he tries, the APP's predictions will 100% come true. He is not predicting the future, he is just reading an unchangeable, cold "script of death tomorrow".
