This is my first fanfic so it won't be to good but please say what you think and I'll write a proper fanfic one day. Anyway this one is how Sans and Frisk are feeling in the Sans battle and what happens when Frisk selects mercy.

1hp Reset. 1hp. Reset. Sans hated it. He knew he had to stop the human from killing everyone. But resets were getting stupid. He had to repeat the same things over and over again. And eventually the human would memorize every single attack. The they would learn to dodge them. Then they would win. He knew it. There was no way to win. He couldn't dodge forever.

It was a pattern. The human selected fight, Sans would dodge. Sans would attack, the human would dodge. The same pattern repeated until eventually the last hit was delivered. By Sans. Then it reset. And it wood all happen again. Fight, dodge, attack, dodge, fight, dodge, attack, dodge, fight, dodge, attack, dodge, mercy. Mercy. Sans hadn't seen it in so long. Mercy. He took the chance. And it reset again. He assumed it was just going to happen once. But no. Again. The pattern had changed. Mercy, reset, mercy, reset, mercy, reset, mercy, reset, mercy, reset.

Frisk p.o.v.

"You have to"

"No"

"It's the only way"

"No..."

"He won't forgive you"

"No"

"He has made that much-"

"NO!"

Frisk had enough. They wouldn't let Chara kill everyone. It may be painful but they wouldn't let Chara win. They couldn't.

Sorry it was so short but the next one should be longer.
