An explosion on a mountain road after a graduation trip made the lives of five young people completely out of control.
After Wen Jia'an woke up from the car accident that shocked the whole city, he found himself in another world - the same city, the same parents, the same friends, but "himself" became another stranger.
In this strange world, all his closest friends have forgotten him. Some people's temperament changes drastically after amnesia, some people are disfigured and disappear, some people live with the disabilities again, and some people are trapped in the past. In order to find the truth, he went to another city alone and met them again.
But as the relationship gets closer, a deliberate murder that has been hidden for many years begins to surface.
Memories, identities, parallel worlds and cracks in human nature are intertwined, and they gradually discover that the accident was never an accident.
But what is truly cruel is not death.
There is only one person who remembers all the past.
Purpose: This work mainly revolves around "loss, memory, growth and loneliness" and tells the story of how people face life and emotions again after losing control of their destiny. Through parallel worlds and suspense elements, the story explores the true emotional connection between people, as well as the pain of "being forgotten" and "remembering alone". Everyone experiences trauma, regret and parting as they grow up, but they also gain the courage to continue living by being with each other. Even if the world is hard to distinguish between true and false, feelings and experiences still exist.
