In the vast ocean of Japanese internet slang and emotional pop culture tropes, few phrases hit as hard as "Gaki ni modotte yarinaoshi." Translating loosely to "If I could go back to being a brat (kid) and do it all over again," this phrase is a key to a very specific, bittersweet genre of media.

We look at our adulthood—the bills, the politics, the burnout—and we remember the smell of chalk, the sound of cicadas, and the simplicity of a juice box after soccer practice. These stories allow us, the audience, to perform a "yarinaoshi" (do-over) by proxy.

The best story in this genre is the one that makes you pick up the phone and call an old friend, or buy that vintage candy you haven't eaten in twenty years.
