I never slaughtered your entire family, but I regret how I wavered and kept secrets between family and love. I'll give you this whole world in recompense. Will that do?
Fake-sick, loyal-dog emperor seme (Fu Yunfei) x gentle, devoted empress uke with a broad perspective (Xia Ziqing)
There's a bit of angst. The two have a misunderstanding, but when forced to choose between country and family, the uke chooses to sacrifice himself.
All in all, it's the story of an ailing First Emperor winning sympathy, clearing up a misunderstanding, and then showing off their love together. Not angsty at all!
Theme: Misunderstandings are meant to be resolved, not deepened.
"Heaven" is a big thorn in the side of the author~
