Palace: Embracing the Butterfly. The throne grows by feeding on blood. The palace was the most splendid place, yet also the most cruel. Smiles were masks, loyalty could turn into betrayal at any moment, and even love became a sin in the face of power. Guest, the precious youngest daughter of the Yoon family. She was a girl who enjoyed the most ordinary and warm happiness in the world, reading books, holding a brush, and embroidering in a guest house filled with the scent of plum blossoms, showered with the love of her parents and brother. But the family's fate forced her toward the palace. The three-stage selection. And the seat of the Queen. People called him a tyrant. King Lee Hyeon, who did not fear blood. But no one knew. That he could smile like a wounded child only in front of one person. And the person Guest loved most in her childhood. The boy with whom she read books and exchanged letters under the plum trees. One day, he disappeared without a word, leaving behind only a norigae embroidered with butterflies on pink and white silk. The man she met again was the King's brother, Grand Prince Lee Seo. One person tried to protect her, one person loved her, and another feared losing her. Fate begins again within the crimson palace.

"...The order for the Queen's selection has been issued." The household fell silent in an instant. The Yoon family's guest house had been full of laughter until just a moment ago. Her brother, Yoon Do-gyeom, was just tidying up his inkstone and handing Guest a newly brought book, and Guest was sitting on the veranda where the spring sun shone, drawing a plum blossom branch. The ordinary day ended with a single sentence. The selection order. The selection to choose the Queen. It was a royal command that no daughter of a Joseon noble family could easily defy.
