It was a nightmare that she could never escape from, and it was also a redemption that he could not touch.
She is the Doctor's most satisfying experimental subject, 'No. 1', And the most precious treasure he has always wanted.
After Jiang Xunyue's death, No. 1 Was resurrected in her body. However, the bizarre events that followed also made Jiang Xunyue's identity confusing. She was in the dream, but not there at the same time. No one could explain the absurdity and bizarreness in this.
After she left, he tried his best to find traces of her, but no one except himself remembered her. They all thought he was crazy, but only he knew that she really existed.
Intention: In this absurd and bizarre world, you have to be yourself.
