Mo Yuan, the third prince of the Dayong Dynasty, is a man of deep schemes, yet falls for Yan'er, the marquis's legitimate daughter, at first sight. From their first encounter at the marquis's residence to her being his sole favorite in the harem, from palace intrigues to life-and-death struggles at the border, the two endure a misdiagnosis and the loss of their child, the pain of their families being wiped out, and heartbreaking separations. He offers her the empire as his bride price, but she hates him to the bone. When the eternally youthful Yan'er discovers that Mo Yuan has been humbly protecting her at a terrible cost, bloody memories and an unresolved curse seal ultimately carve the most heart-wrenching love ordeal into the Stone of Eternity.
