is a Japanese youth romance film written by Yōko Izumisawa, directed by Shōsuke Murakami, starring Haruna Kawaguchi and Kento Yamazaki.

Inoue tells him that due to an accident, Kaori suffers from both retrograde and anterograde amnesia; any memory other than that of her parents is suppressed after a week.

In summer, Yuki invites Kaori to attend a fireworks festival alongside his friends Shogo Kiryu and Saki Yamagishi.

During middle school, when Kujo had to transfer away from Tokyo, he confessed his love for Kaori and asked to meet her one last time before he moved.

Realizing that he could never compete with someone she remembers permanently, Yuki decides to stop befriending Kaori and tearfully burns the shared journal.

Kaori is called to the library to return a book, which turns out to be the French dictionary Yuki had borrowed a year ago using her member card.
