In order to complete the task assigned by the organization, Tan Ninggui, a scientist from the BHS Foundation in the beta paradox space, came to the three-dimensional human world single-handedly and found her candlelight - Chun Yingnai - in the dark and complex human nature. She found beautiful things in the darkness, and Chun Yingnai became the light in Tan Ninggui's life besides science. At the same time, the arrival of Tan Ninggui also made Chun Yingnai feel warm. Chun Yingnai had a gloomy childhood, but Tan Ninggui made her youth not gloomy. They discussed human nature, science, literature and philosophy, and talked about the past and the future. Inadvertently, Tan Ninggui revealed the truth of the world to Chun Yingnai. . .
Intention: Long live truth and science, human nature has both darkness and light.
