This work is mainly used to listen to the author's call. It has no real meaning and serves as a mood diary. Mainly essays. The title of the work is a piece of advice to the author.
The past and present that we are nostalgic for will definitely become the missed moments in the future.

Comics: A type of fan fiction. That is, several animations are combined together to become an independent space. For example, characters from anime such as "The Prince of Tennis", "Ouran High School Public Relations Department", "Detective Conan", "Lelouch of the Rebellion" and "Tutor" appear in the same world.
Or the protagonist travels through various coincidences into "Bleach", "Twelve Kingdoms", "Inuyasha" and other anime that cannot be combined. Such as "Wordless Puzzle", "Thousand Changes", etc. There are also comprehensive comics created with the original protagonist of a certain anime as the protagonist, such as "The World Only Keima Katsuragi Knows".
The protagonist may be someone who has traveled through time in the past, or is an aborigine (a non-anime character who lives in anime or an anime character). Those who have traveled through time may or may not know the plot. Most of the aborigines do not know the plot, but some fans have some precognitive abilities or other memories of the female characters who have traveled through time to let the aborigines know the future of their world, which is the plot.
Go coo, coo, launch an attack on the world!
