Scientist - GASTER X READER

Thanks!

You saw your bag on the red worn-out sofa near the tv, underneath a Y/FC, fuzzy-looking, turtle-neck sweater. It was really cute, not to mention that you needed a jacket or sweater, too. Ignoring it, you wanted only your bag, so you took the sweater away, only to see a little note that was behind it. The letter was in Wing Dings font, so it was hard to read, yet you tried to understand and your final translation is;

"Greetings, Y/N. It is a little bit cold outside, so you might want to use a sweater. You're in Snowdin now, are you not? I am hoping to see you soon.

-W.D.G"

"Huh? who would give me such an cute little sweater, I love it. Thank you, mysterious person~!" You hummed in a jolly tune as you wore the sweater on. It was really comfy, you felt protected and loved...

You came outside again to cherish the amazing view, "Snowdin, huh?" You said while taking a little stroll in the town. There was so many amazing things to do, and creatures to talk to, even if it was just a tiny town.

"Hey, punk! E-ehheh I meant Y/N... this is all of the sudden, but could you help me get my hot choco mix at my house over at the Waterfalls? It's really nice here today in Snowdin so why not take a cup-of-yummy-choco for today?" Undyne asked you in a shy way, while scratching the back of her head.
"Sure, why not?" You smiled at her and nodded.
"Glad! So, ya see, Waterfalls' this way. Be careful, this path is really cold." Undyne held your hand as she pointed the direction.

On the way, there were snow, more snow, some weird games? or puzzles that seemed activated, little booths, snowpiles, and dogs. It wasn't long until you two got to the waterfalls, and it was a long walk.
