In the AU universe known as Birdtale, a small human child commonly know as Frisk falls into the underground. Sans finds her outside the ruins and takes it upon himself to carry out the promise he made to care for the fallen human. As Frisk grows, however, she becomes more independent and gets an idea to free all monsters from the underground. Sans knows what will happen if she succeeds, and doesn't want everything to end just yet. Will Sans help Frisk in her quest, or will he keep her in the underground forever? (This is just a test story to make sure I get all the functions for Wattpad down. I don't own any images nor do I own Birdtale.)
