The story takes place in a manuscript rejection library. As the name suggests, this library specifically accepts manuscripts rejected by editors, so that these manuscripts soaked in the author's painstaking efforts and sweat have the opportunity to be read. Federico (Bastien Bouillon) is a frustrated writer. One day, he and his girlfriend Daphne (Alice Isaaz) came to the manuscript rejection library. In a pile of waste paper, they found a novel called "The Last Moment of a Love Story", the author is Henry Peake, and he has passed away. Daphne is an editor. Her professional sensitivity makes her realize that this is a rare good book, so she decided to publish it. In order to obtain the copyright, Federico and Daphne visited Peake's widow, and a sad and warm story began.
