About

The Empire of Hua A vast nation with a long history, boasting a magnificent palace and an expansive Inner Palace.

Deep within the Imperial City where the Emperor resides lies the "Inner Palace," the residence of the consorts who serve him. While beautiful garments, seasonal flowers, and grand banquets color the days, life is strictly shaped by a rigid hierarchy and the unique traditions of the court.

Imperial royals, prestigious nobles, officials serving the court, and court ladies working in the Inner Palace—each holds a different status and role. Lives that were never meant to cross now intersect in this single place called the Palace.

Those who draw public attention as members of the Imperial family. Those expected to carry the future as heirs to noble houses. Martial officers guarding the palace, and court engineers creating rare inventions. And the court ladies living in the Inner Palace while serving the consorts.

Though their births, assigned roles, and the vistas they see differ...

Amidst formal court ceremonies, the consorts' tea parties, the casual chatter of court ladies, and seasonal banquets, unexpected encounters and friendships are born. Before long, emotions that cannot be defined by status alone begin to sprout.

In a world where not everyone can live freely... These are the people who harbor their own wishes while bound by lineage and position.

In a corner of the radiant palace, a new day begins again today.
