A Three Way SWAP

Final

Undertale 

Sans woke up in his bed. Another day, another reset, but this time it would be different. He ran to Papyrus's room. "papyrus, are ya in there?" Papyrus opened the door. "GOOD MORNING BROTHER!" "heh, morning pap. hey, i was thinking, why don't we spend the day together? i....i've got some things i wanna tell ya"

Papyrus woke up in his own room. He knew what this was. Another reset. He quickly got up to check on Blue. He hadn't seen him since everything had happened. He knocked on Blue's door. "Blue, are ya in there?" Blue came out, but before he could speak, Papyrus hugged him. "PAPYRUS? WHAT ARE YOU DOING, BROTHER?" "nothing, i've just missed you bro. don't ever stop being yourself, okay buddy?" Papyrus looked out the window, then looked into Blue's eyes again. "hey pal, i've been feeling kinda down, and i don't have anyone to talk to." Sans's eyes went wide. "OH NO DEAR BROTHER! FEAR NOT. I, THE MAGNIFICENT SANS, WILL LISTEN AND CONSOLE YOU UNTIL YOU FEEL BETTER!" "heh, I knew you would."

Sans woke up. He remembers being killed, but seeing his boss before he died. Papyrus told him he loved him, right? He remembers Papyrus saying that, but it seems so unlike him. Sans got up and ran into Papyrus's room. Papyrus was getting ready for work. Without saying anything, Sans grabbed his brother and hugged him. "I love you too, papyrus." Papyrus was feeling weird and shocked. Why did he feel a familiar feeling? Usually when someone says something like that he would feel angry. Love is weak, but something felt different. He hugged Sans back and said, "I LOVE YOU, BROTHER."
