Three years ago, a diagnosis of "malignant tumor" and a hasty funeral made architect Lin Xi completely "dead" in Lu Chengyu's world. He is a well-known rational leader in the investment banking industry, but he is only worried about her departure, and there is always an unspeakable doubt in his heart.
Three years later, Lu Chengyu met single mother Su Wan in the rain alley of the old city. She had her long hair cut off and had a slight scar. Her temperament was as calm as a stone smoothed by time. She was holding a little girl beside her, Nian Nian, who had a familiar look on her face.
He told himself that this woman had nothing to do with the bright and warm Lin Xi. But her way of peeling an apple, the old tune she hummed unintentionally, her focused eyes when looking at the drawings, and even her actions to subconsciously protect him in critical moments were all like fine needles piercing his sanity.
Su Wan tried his best to hide the past, using the identity of "Su Wan" to protect Nian Nian and avoid the shadows in the dark. She was afraid that Lu Chengyu would recognize her, and she was even more afraid that he would know the truth behind "death" - the hardships and helplessness hidden in that carefully planned separation.
When Lu Chengyu's concern for "Su Wan" gradually gets out of control, when the children's words he misses tear open the cracks in his memory time and time again, when the black hands behind the scenes are closing in step by step, the two people wrapped in lies and longing will finally see the light that has never been extinguished in the fog.
She is the white moonlight that he thought had passed away long ago, and he is the old dream that she dare not touch again. Is this reunion that begins with "death" a joke of fate or an echo of love across time? A million words are carefully laid out to see how love and redemption break through the fog under misplaced identities.
