He Will Always Love You (Humantale Sans x reader)

Sans and Papyrus have been letting you live in their house for quite some time now. You've seen their feuds, their good times and their bad times. Their hardships, and their disagreements. You've been able to get close to both of the brothers, especially Sans. He's told you all his secrets and you've told him all of yours. Sans is the only one that you trust, he was the first person that you met after your dad threw you out of his house. Sans was basically your first best friend. And not even that, he was your first huge crush, and you'd do anything to let him know.
