Hearts On Fire - An Undertale Sansby Fanfic

Sans is a regular at Grillby's. He goes there all the time, nearly every day. He goes there so often that he and the owner, Grillby, have become like best friends. They chat, Grillby brings him home when he's drunk whenever Papyrus is unavailable, and pester each other a lot, just for shits and giggles. But both of them have stronger feelings that they're afraid to tell the other about, scared it could ruin their friendship that they had built so strongly over the years.

This book will contain other ships of mine. If that's a problem, the door is right over there. (points)
Dear god, why does every single Sansby fanfic have a fire pun in the name...
