In the summer of 2009, Mosquito, who gave up college due to family changes, entered the county library to work. She always finds old books with pen creases in the ancient book restoration room, and the borrowing record always stays on August 17, 2009. Until one rainy night, a mysterious young man who called himself Xiaojie knocked on the iron door of the library with "Snow Country". The two began a text game that spanned life and death through the handwriting on the library card.
When Mosquito discovered that Xiaojie's manuscript was actually a fictional novel recording the encounter between the two, the other party had disappeared during the rainy season due to a terminal illness. Four years later, she returned to her hometown with an unfinished manuscript, only to find her photo engraved on Xiaojie's tombstone in the cemetery - it turned out that he had secretly changed his library card when they first met, and used sentences from her high school composition to predict the ending.
Intention: Those who use words to fight death will eventually be nailed to eternal regret by words.
