Lin Xiaoman has lived for 16 years, but his biggest worry is not that he failed the exam, but that "memories always leave home" - the ancient poems he just memorized are forgotten when he turns around, the notebook he just bought yesterday can "evaporate out of thin air" in his schoolbag, and even the hot pot he ate with his best friends last week, the details are blurred like mosaics. The teacher said that she was "not focused on studying" and her classmates teased her that "the memory of a fish lasts longer than yours". Only Lin Xiaoman knew that those disappeared memories seemed to have been secretly "took away" by something.
It wasn't until the transfer student Jiang Che sat next to her that everything started to look different. This boy who always wears a clean white shirt and has a thin silver chain wrapped around his finger can always tell her accurately when she can't find something, "Your math paper is next to the mop pool at the back door of the classroom" and "The hairpin you lost is in "The Little Prince" on the third row of bookshelves in the library." What shocked Lin Xiaoman even more was that she accidentally saw Jiang Che using the thin silver chain to "fish" a shimmering fragment out of the air - the moment the fragment entered her mind, she suddenly remembered the appearance of the rag doll she lost when she was three years old.
