You were the human that got everyone to the surface. Everyone was ecstatic except for Sans, who was lazily drawing in the sand with a stick. That was to be expected though. He probably still thought that you'd reset the timeline again out of boredom even after the many times you assured him you wouldn't. For that reason alone you decided to give him a gift to cheer him up. A flower crown!

You walked up to him, and he immediately sensed your presence as usual and looked up. His left eye's pupil flashed a vibrant blue for a short moment before returning to it's usual white.

"Hey, wassup kid-"

Before he could finish calling you by your nickname, you placed the flower crown on his head gently. He tensed for a second before relaxing and chuckling, "You're really spendin' your time on me these days, ain'tcha kiddo?" He ruffled your hair in a playful manner with one of his boney hands. It was a little cold, but you got used to that feeling already. After all, he was a skeleton. What else did you expect, hm?
