One Day, My Husband Suddenly Brought Home a Mistress…

“I intend to keep this girl as my mistress.”

It has been three years since Sienna became Empress. Betrothed to Crown Prince Arnold since childhood, she devoted herself entirely to supporting him as he rose to the throne and became Emperor. Throughout it all, Sienna held herself to the strict standards expected of an empress, yet even now, the two still had no children.

Her trusted lady-in-waiting, Emma, often speaks of her wish to remain unmarried and dedicate her life to her work. Each time she hears those words, Sienna finds herself wondering: If I had simply been born the daughter of an ordinary noble family, could I have lived that freely as well?

And just as such thoughts begin to linger in her heart, Arnold suddenly appears before her, hand in hand with a charming young noblewoman, calmly delivering a declaration that shatters the quiet order of the palace.
