Étienne Vallière, a man haunted by a lost love, returns to Paris after twelve years to unravel the mystery of Celeste d'Aubert, a woman he once adored who vanished without a trace. His search leads him to a forgotten house on Rue des Ombres, where time and memory have entwined in strange and inexplicable ways.
In the crumbling mansion, Étienne encounters Celeste-or what remains of her-a woman who has not aged, her presence lingering like an unresolved dream. The house holds more than just her memory; it is a place where forgotten promises and long-lost fates resurface. The scent of violets, the whispers of old poetry, and the heavy shadows that move like living things all hint at a deeper connection between Étienne and Celeste, a love that seems to transcend time itself.
But as Étienne uncovers secrets hidden in the dusty corners of the mansion, he encounters a mysterious figure: a man in black, a keeper of forgotten things, who reveals that Celeste is not just a woman, but a being tied to the eternal threads of fate. Her love with Étienne was never meant to be fulfilled in this life, and his unrelenting search for her has cursed him to an eternity of longing.
Torn between love and despair, Étienne must confront the truth of his bond with Celeste, the price of love that transcends time, and the forces that seek to keep them apart. He is faced with an impossible choice: to let her go forever, or to keep searching for her through the ages, bound by a curse he cannot break.
