It's a sand plot flow, CP: Readers can just stop here, the male protagonist does not have an official CP
The sand sculpture emperor praises his beloved concubine (man) all over the place due to obsessive-compulsive disorder
[The main characters and the main supporting characters are all male]
Excerpts from the clip: Eunuch B: Report to the Emperor that Concubine Zheng and Concubine Chu had a bloody fight in the harem!
Sui Changdi: Are these two men and women?
(There are too many people in the harem, both men and women, so I forgot about it)
Eunuch B: They are all men.
Sui Changdi: OK! As a concubine in the harem, I don't have to be pampered, but I often compete with each other and exercise, so I can be so healthy! Especially this Concubine Zheng, she didn't shrink back just because the concubine was superior to him. That's amazing!
Concept: The emperor is obsessed with praising his beloved concubine (a man)
