At midnight, No. 99 Shiyi Lane - Time and Space Shiji Office opens for business.
Shen Zhiwei holds the "eye of tracing light" in his hand, traveling through modern times, eras, the Republic of China, and ancient times, and inherits the regrets of the world: a jar of sugar from 1988, a stack of unsent love letters, and a wedding dress that has been sewn for a lifetime but has never been worn.
There are traces of her in every time and space, but she never remembers being there.
What's even weirder is that her own note appeared in the sugar bowl: "Don't open the sandalwood box."
There is also a mysterious man in the office, Xie Wuwang, who is as gentle as jade and has a thousand-year-old scar on his wrist. Before each time traveling, he said, "I'll wait for you to come back." When he came back, he would hand him sweet-scented osmanthus tea that was just the right temperature.
"Who are you anyway?"
"Mirrorkeeper." He smiled, "I've been waiting for you for a thousand years."
When the 40th mark lights up, the truth tears apart the tenderness——
Thousands of years ago, she was the God of Creation, and she personally formulated ninety-nine and eighty-one perfect rules. He is her fiancé, who has become a mirror keeper for a thousand years of atonement due to his sin. She sealed her heart in a sandalwood box and spread her soul into every time and space.
"81 Fulfillments are the wishes I made. May you witness the worthiness of the world and learn to love me."
