Ding Chong Xi and Lin Yu, who have gone together through high school until college, are struck with a tragedy, when after a car accident, Lin Yu ends up in a coma. Using virtual reality, Ding Chong Xi uploads Lin Yu's consciousness to an alternate reality, hoping to wake her up that way. But instead, every time Lin Yu is on the verge of waking up, a script is triggered, the whole reality is restarted, and Chong Xi needs to start everything from the beginning, over and over again. Things take an even worse turn when the boy discovers that all those restarts have consequences, and the chances of saving Lin Yu become slimmer with every try.
