I have always felt that Si Si was a heart-wrenching child, and I felt that De Concubine was quite annoying, so I wanted to write a story about traveling through time and becoming De Concubine. But when I was thinking about Concubine De's psychology, I felt that she had no choice but to make such a choice. I felt that she actually had to make that choice, so I wanted to write about Concubine De's psychology to defend her reputation as a "bad mother".
But I also feel that what Concubine De did when Yongzheng ascended the throne was too tragic for Sisi, so we have a time-travel heroine to change this!
