Wen Jing is a unique "memory weaver" who can reconstruct forgotten or broken memory fragments for clients through smell, sound, light and shadow. Her studio "Floating Light" is hidden in a corner of the city. Outside the door are the fireworks of the world, and inside the door is the depth of time.
One day, a special guest broke into her world - Shen Xiuze, the heir to the Yuanxing Group. He brought with him a blank memory that had troubled him for many years and a strange fragment - the fishy smell of mud after the rain and the crisp sound of a bell. He was cold, suspicious, and yet painfully aware of the blank space.
Wen Jing accepted this commission with professionalism, but she never imagined that when she dived step by step into Shen Xiuze's dusty memory, she would not only find the truth about him, but also a shocking secret closely related to her life experience. A huge fire fifteen years ago, a promise that was deliberately erased, and an "accident" that changed the fate of two people.
Fragments of memory began to flash back in her own mind, and the childhood nightmare she thought she had long forgotten was actually tightly entangled with him. When danger quietly approached, trust and betrayal intertwined, and love and hatred pulled at each other, they discovered that what he was trying so hard to remember was exactly what she was trying so hard to forget. In this puzzle woven by memories, they are each other's only salvation and the most deadly poison.
