When Xu Zhiyi woke up, she found that she had been kidnapped by a strange and familiar man. He called himself Jin Siyan and took her on a ship to England, saying that he would fulfill their agreement - to travel around the world and see the Aurora. However, Xu Zhiyi was convinced that she had never seen him.
As the journey unfolded, Xu Zhiyi discovered that Jin Siyan knew her likes and dislikes very well, as if he had known her for a long time. Under the aurora in Norway, she suddenly had a splitting headache, and fragments of memories came flooding back: When she was eighteen years old, she had agreed to watch the aurora together with the neighbor boy "Akin", but she became a vegetative state in an accident, and lost the memory of those two years when she woke up. And Jin Siyan is the forgotten "Ajin".
When the truth was revealed, Xu Zhiyi realized that this was not a kidnapping, but an affectionate confession from a schizophrenic patient who tried his best to awaken her memory at the last moment of her life.
