Snow on the Vermilion Walls: My Husband Is the Emperor

This is not a simple love story, but a tale of strategy and rivalry built around “dimensional superiority.” The heroine, Shen Qingyi, puts modern psychology, management, economics, and even basic science to use. Amid the treacherous intrigues of the imperial harem, she transforms from a pawn into the player directing the game. Together with the equally brilliant emperor, Murong Che, she moves from mutual scheming to a profound union of souls.

(The romance develops rather slowly at first.)
