Holy shit. I've only ever cried 3 times from literature before this. This isn't even a professional book, and it made me cry. THAT'S how good it is. NOT EVEN THE UNDERTALE GENOCIDE ROUTE MADE ME CRY. Holy damn this is good.

in underswap, the skelebros' cases switch. not the fonts though. but the MAGNIFICENT SANS TALKS LIKE THIS, and papyrus like this, see? just so you know.

OMG, Poor Papyrus! It was like I could feel his pain as he went in to find his brother's dust all over the floor! And the fact that he genuinely thought that it was a really bad joke at first. It hurt so badly! And then watching everyone else fall at the human's hands.
The whole thing was heart-wrenching!

And OMG, Sans! How could that jerk human do that to him!? He was HAPPY. Doesn't the human realize how rare it is to see Sans REALLY and ACTUALLY happy!? The poor baby! He didn't even see it coming! There was no warning, just pain. And Sans dies in shock.

Nah, I don't think I could've watched, following the human as they made their way through. I like to think I would've jumped in. Help Alphys take them down. That human would never have made it to the final corridor!

. . . . that jerk. I am glad that Papyrus didn't say a damn thing before the battle. The human doesn't deserve words. They deserved to be burned to a crisp. And still Papyrus lost . . . because that's how these things go . . . Damn it.

Beautiful job! So many feels!

Quite touching. Underswap is too sweet a universe for genocide.

Man this human is as dumb as a sack of killer bricks. They couldn't figure out the switcheroo? They are in for a bad time.

Awww, this was so sad! But at least the ending was happy... :)

The saddest part for me was the "but nobody came." Whyyyyyy? To much feels! T-T

This...was...SAD/BEAUTIFUL! Waahh! Why human why?! *takes a deep breath* This was pretty good. Two thumbs up!

*gross sobbing noises*
This is one of the best Underswap AUs I've ever seen! I've really been looking for a good one, but none of the others could match this! Can be very comedic, very dark, very spooky, very emotional. I must admit, that I cried a little...a lot...omg I cried everywhere. And Alphys's last words just shattered my heart! But the end really got me. The final battle, and the reset! It got very intense!

I loved the build up you had to Alphys death and how Chara still acted innocent after murdering Sans. Alphys last words were also heartbreaking. Then the fight with Papyrus was really cool. It was crazy how Chara survived the gaster blasters with the 0.001 HP. Wrapping up the chapter was good too. It was a great chapter, I couldn't find any flaws.

That was weird to read...everything I saw the words 'the great sans' my head feels dizzy because I just can't see sans like that it's just weird...for this I congratulate you and your amazingly confusing work.

I did not expect Sans to be killed after the date. AND WHY DID YOU MAKE ME CRY. I reall hope you continue this story and that Papyrus gives Chara hell.

This story was amazing. I love the Underswap AU, and I think Sans is adorable. This story was amazing, the idea of a glitch in which everyone swap roles in the game was an excellent idea. Good work on the story! Definitely a favorite!

First off, I really adore the fact that this is an Underswap story! It's my favorite Undertale AU, and I knew I had to read it when I was looking around. Not a lot of Underswap stories out there, y'know?
I just can't stress how much I love this story. I feel that you portrayed the charactes pretty well, adding their own little twist to make them more than just 'swaps.' As I went through the story I began to feel sadness, and when Pap was recalling all of the quotes Sans had said made me burst into tears. I began thinking "what would I think if my little brother was suddenly dead?" The sad feelings grew even larger when the memorial was performed.
This was an incredible one-shot, and I thoroughly enjoyed reading it all! Keep up the good work for all of your stories~
