In a future world called Estela, time no longer flows linearly, but is controlled by a powerful "lock of time", ensuring the stability of history and the balance of the world. The protagonist Alison, a young history scholar with the ability to read past memories, accidentally discovered an ancient diary, which recorded a forgotten secret - a mysterious device that can unlock the shackles of time and reverse the course of history. Following the guidance of the diary, Alison embarks on a journey to find the "Lock of Time". Not only does she have to fight against the Dark Council who attempts to tamper with history and control the future, but she also faces the shocking truth about her own life experience. In the process, she met several key partners: Sebastian, a technical genius who can manipulate time fragments; Leia, a warrior from ancient times who has fighting skills that transcend the times; and Noah, a gentle psychologist whose ability is to heal people's wounds and help them face their deepest fears. They travel through different eras, from glorious ancient civilizations to distant future cities. Each era hides key clues to unlock the mystery of the "Lock of Time." However, every attempt at time travel causes the "time rift" at the edge of the real world to expand, threatening the stability of all existence. Alison and her team must find and close the "Lock of Time" before time completely collapses. At the same time, they also have to make a difficult choice: let history take its course, or bravely change the past for the greater good?
