Young Marquis Shen Zhao is betrayed by his closest friend and meets his end with a cup of poisoned wine. In his final hallucination, he sees the palace gates from when he was sixteen, and the young emperor handing him a warming brazier.
Reborn, he finally sees who truly cares for him. He remembers the things he must never do, keeps watch through the long nights, and tends to the emperor through illness, awkwardly yet fervently pursuing that dignified, godlike figure. The emperor goes from bewildered to indulgent, and at last falls in love.
A white jade hairpin seals their vows. From then on, they face wind and snow together until their hair turns white, never parting in life or death.
A thousand years later, the jade hairpin remains as smooth and lustrous as ever in a museum. In the glass reflection, it seems two people walk hand in hand: a love that crossed the boundary of life and death and will never fade.
