Sans has seen a lot of resets. Of course he has. The many routes Frisk takes. Ones where they kill everyone, besides him of course because he’s far stronger, and ones where they save everyone. It’s strange, well, it was at first. After so many resets, he had practically gotten bored of them.

However, this reset was….more than strange. Shortly after Frisk falls into the Underground, so does another. Although you are older, older than Frisk. Ever since your new face popped up into this reset, he has been cautious. Who are you? Are you aware of resets, too? Or maybe….you’re a monster as well, but just looks human? Do you have magic?

Too many questions, so little time to gather answers. Although, he would rather keep his distance and get his answers from afar.A few months after you have arrived, he has noticed how fond you are of him. And, well, you have certainly given him hints of your crush with him, but he always ignores them or brush them aside. He doesn’t know how he feels about you, honestly. Although he is cautious, he can’t help to…be fond of you, too. The way you take care of Frisk, or treat monsters as equals…your kindness, too….it’s….adorable.

But, he needs to keep his distance. He needs to stay on guard. He needs to…

His thoughts are interrupted when he hears a knock on his bedroom door. He glances up at the door lazily, studying it for a moment. It’s you. He can tell by the feel of your soul. Not that you would know that. Instead of answering, he raises his hand and swings it around, using his magic to swing the door open. A blue glow covers his finger and the door, showing the connection with his magic. And when it opens, he sees you standing there.

“Oh….uh, hey Sans,” you smile warmly, greeting him. You don’t go into his room often, given he doesn't want really anyone in there, but on a rare occasion he allows it.

“Hey, kid,” he greets lazily, as usual.
