The Duke Isn't That Cold

The empire's duchess wins people's hearts through her own strength.

She crushes the rebels, advances the Industrial Revolution, and champions constitutional monarchy.

She devotes herself tirelessly to her people, earning their adoration, with admirers beyond counting.

Yet she is utterly indifferent to love. Even when its flames burn her, she feels nothing.

Then one day, she finds a girl who is her complete opposite.

From then on, she dotes on her little sister so much that heaven and earth are outraged, leaving the whole country stunned.

Her sister never stops vying for her attention, and every day brings a new battlefield.

The crown prince is one thing, but even a scheming demon king wants to compete to become her brother-in-law!

The duchess is adored by everyone, with no rivals in love throughout.

A healing, lighthearted start, followed by political intrigue and revolution.
