Five years ago, when Gu Su received the news of her father's death, an anonymous email broke into her broken world:
"Look up after crying, the light is in the direction of 16:20" - signed Lumos
She didn't know that the sender, Xi Ran, had just buried his mother in the cemetery next door and was typing these words of comfort with his blood-stained hands.
Five years later, on the autopsy table in New York.
The ascetic assistant teacher Xi Ran's white shirt collar exuded a faint scent of jasmine.
When his scalpel covered her trembling hand and cut open the chest of the cold specimen——
"The edge is inserted at 45 degrees, just like the diagram you drew incorrectly in your senior year of high school."
Gu Su's pupils suddenly shrank: That was a private email she sent to Lumos!
Purpose: "Light the lamp of the heart in the abyss of human nature, and use love as the blade to pierce the eternal night."
