A fan fiction of Oikawa and Iwaizumi, that will tear your heart in two. Make you cry for hours on end. Also after reading it, the song (specifically the piano version of it) A Thousand Years by Christian Perry will make you cry every time you hear it.
"Hey! Have you read the fanfic Best Mistake?"
"Ack! Don't remind me of that, I cried for days on end because of that fic!"
