Chapter 46 ~ Underfells, of Day One - Alpyhs

Oh my god I'm rereading the final chapter I wrote. Not only is it perfect, but I cry every time I read it ohmylord the feels. [I have to read it to be on track with the plot] anyways, you can attempt to guess the ending but you'll never get it

Also this song is beautiful. Thanks for telling me about it.~ This is literally my favorite song of all time now. Theme song right there; Also, we're #365 in fanfiction! I never thought this book would rise this high. I have all of you to thank for this!

This chapter is dedicated to RealityTraveller. You have commented thousands of times xD You're not too bad!

This is literally my magnum opus of endings. You will not be disappoint.

Magnum Opus: a large and important work of art, music, or literature, especially one regarded as the most important work of an artist or writer.

As you sat eating cinnamon buns with Uf!Undyne, you two had grown quite close. She was talking about that time that Uf!Alphys had blown up a gas station.

"It was some sort of chemical compound or whatever. We had just come to this world, our first time above-ground and we were scattered... separated. Basically, we landed on the road and then basically ended up blowing a gas station. IT WAS EPPPPPIC!"

"Sounds like it!" You laugh, biting into one of the cinnamon buns. She grins that usual toothy grin of hers, but it slowly falls into a sadder face. "What's wrong?"

"You... I never expected it to be like this, ya'know. Uf!Sans and Uf!Papyrus.... I thought they'd been brainwashed or something. Not.. just this. What do you call this?" Uf!Undyne muttered. "I'd like to show her. Uf!Alphys, I mean."

"You know..." You begin, wondering how you were going about this. "The original you and Alphys hook up after you guys leave the underground. Maybe...?" You raise an eyebrow, and Uf!Undyne cackles and looks away quickly.

"Nah. Uf!Alphys... I think this Alphys is straight." Undyne's hands tightened into fists, and her claws sunk into the fabric of her pants. "I just don't know what to do." Uf!Undyne murmurs.

"Well, you can't anywhere just by wishful thinking. You have to talk to her." You urge, and Uf!Undyne looks up at you, her expression one filled with surprise.

"You're right. I should just talk to her...! I'm gutting myself here with worry over whether she'll like me or not, and I haven't even done anything!" Uf!Undyne stood up, and literally took down her door, running down the hall.

"W...wait! Undyne, I didn't mean now!" You ran after her and witnessed her flip an entire foodcart over. She vaulted over it, ramming into Uf!Papyrus and kicking Uf!Sans in the face.

"Gotta go, LOSERS~! I'VE GOT A DATE WITH A DINO!" Uf!Undyne laughed, maniacally. She then punched Uf!Papyrus in the face, to match his brother. She dashed past.

"@#$%$, @#$@!@, #$%^^%. %^%$#@!" Uf!Sans let out a string of curses which included bad words. "The next time I see you, Fishsticks, I'm gonna stick you in a f$#!$#cking MEAT GRIIIIIIIIINDER!" He screamed.

"Sorry, Uf!Sans." You give an apologetic smile, and he gives you an off-sided glare.

You ran ahead, totally not apologizing to Uf!Papyrus. He could handle it. You turned the corner, and Uf!Undyne winded back, punching the door and literally blowing it to pieces as she dashed into the room.

"AAAAAAAAAAAAAAAAAAAAAAALPPPPPPPPPPPPPHYS!" Uf!Undyne roared.

"WHAT?!" Uf!Alphys snapped. "WHAT THE HELL DO YOU WANT, UF!UNDYNE?!"

"I.... ALPHYS, I LOVE YOU!" She screamed. You watched from the doorway, astounded. She just...did it.

"ABOUT F*CKING TIME, TOO, GOD DAMNIT. I'VE BEEN WAITING FOR F*CKING EVER YOU F*CKING PIECE OF F*CKING SHIT!" Uf!Alphys slapped Uf!Undyne, then kissed her. "HUMAN EXPERIMENTATION MEANS NOTHING. I'D RATHER BE EXPERIMENTING WITH YOU, AND THAT IS WHAT WE ARE DOING FROM NOW ON."

"Deal. This was my fault for not saying it sooner!"

"F*CK YEAH. I'VE BEEN WAITING SINCE WE WERE F*CKING PRETEENS, YOU B*TCH."

This was the strangest thing you've ever seen.

"WILL YOU CHANGE YOUR WAYS FOR ME, ALPHYS?" Uf!Undyne got on one knee, and checked her pockets. She pulled out a poptart. "WILL YOU MARRY ME? YOU'RE THE ONLY ONE FOR ME. THE LOVE OF MY LIFE!"

"ARE YOU PROPOSING TO ME WITH A F*CKING POPTART?"

"YES!"

"F*CK YES! I WOULDN'T HAVE IT ANY OTHER WAY!" Uf!Alphys literally swept Undyne off her feet, and gave her a massive kiss. "POPTART WEDDING, HERE WE COME!"

What. Just. Happened.

What did I just do?
