She was the fifth legitimate daughter of the Regent's household, foolish and dim-witted, despised by everyone.

She was a top agent from another world, cold and ruthless, feared by everyone.

One confessed her love in the street and was slapped to death by a scumbag.

The other was betrayed by a friend and died unexpectedly in an ambush.

When a soft, foolish identity merged with a fierce, cold-blooded soul, heaven and earth changed color.

By day, he was a sickly prince who received no respect. In secret, he controlled a shadow organization that struck fear into people's hearts.

He wore a mask year-round, endured humiliation, and plotted his grand ambitions.

But her arrival became the greatest uncertainty in his plans.

At last, she asked him coldly, "Do you want me, or the throne?"

His gaze was firm. "I want you. I'll conquer the realm and give it to you."
