Li Jinmu happened to learn that the person she had loved in secret for ten years, her unrequited love, had died in a car accident. Heartbroken, she recalled every moment they had shared, unable to let go. Then a miracle happened: she returned to her high school days. She didn't know whether it was a dream or whether she had died, but she didn't care. She only wanted to find the person she loved and make up for the regret that had haunted her for ten years. If she had truly gone back in time, she wanted to help him avoid that accident and live a good life.
