(This will be short I'm sorry very sorry)

(Y/N) POV
Running around the park with mom is so amazing! But *BOOM!!!* lighting and dark clouds surrounded us and...it started to rain...but a kind Man put his umbrella above us I looked at him and said

"Thank you!"

And hugged with glee, he returned the hug and he told me

"Kiddo I will see you later"

then when I blinked he disappeared into thin air.

Sans POV
I saw a kid and their mom in the rain so I had what I had to do...I put my umbrella above them and the kid told me

"Thank you!"

With a hug I hugged back and told her "Kiddo see you later", And when she and her mom blinked I teleported
To my house waiting for the little girl to fall asleep.

TEM SKIP

Still Sans POV
The kid fell asleep and I went to her dream and we hung out and talk in her dream but when it was time I hugged her and let go I put my hand over the left side of my face and to let go only to reveal the side of my face was my skeleton face I said to her "Don't Forget me" and then she woke up...

(Y/N) POV
I woke up to find that it daytime already I told myself "I really thank him though"

I'll never forget you
