Lily and Yu'an had the same dream when they were young, but they took different paths at the crossroads of time.
Lily once longed for stability, but she endured the quagmire of marriage for half her life, and finally turned the feathers on the ground into words; Yu'an stayed true to his edge, reinvented himself with a clear mind in a foreign country, and never forgot the promise he made when he was young.
They have gone through completely different lives, experienced betrayal, brokenness and distance, but they have always been the most secret mirror and the hardest armor in each other's lives. When the white-haired Lily crosses the ocean and smiles at the same old Yu An, the jealousy, fulfillment and redemption buried by the years have all turned into the deepest bond in time.
Purpose: In a world full of prejudice and mud, women use each other as the fulcrum to fight against mediocre fate and achieve symbiotic growth.
