Soma Sara, a high school girl transported to another world, finds herself entering the imperial harem as a stand-in for a noble lady who bears a striking resemblance to her.

Her immediate concern isn't escaping the harem, becoming the Emperor's favorite, or even returning to Japan. Instead, it's "How can I make my beloved Emperor happy?"

This is the story of an earnest and naive girl who, convinced that "He'd surely be happy if all his beautiful wives got along!", neglects her own self-improvement and busily strives to foster harmony among the imperial consorts.
