My other side (An Undyne x Papyrus fanfiction)

Undyne and Papyrus have been best friends for as long as they can remember. But with her duties with the Royal Guard keeping her busy, Undyne doesn't seem to have much time for Papyrus anymore since the war started.

But when a small girl comes to the underground, Sans sends Undyne a message saying that he's worried about Papyrus, as he seems to be becoming acquainted with the small girl. With her friend on her mind, Undyne vows to protect Papyrus. But with her guard duties, she still rarely gets any time to check up on him.

One day, she returns home from a day at work and begins to prepare for Papyrus's training/cooking lesson.

But as the hours go by, Papyrus never shows up. Undyne begins to get worried, and goes to where he was seen last only to get there and find Papyrus slowly dying.

After Papyrus leaves her, Undyne is given an opportunity to go back, with a few things about the past altered. Not thinking about the consequences of resetting to before Papyrus died, Undyne accepts the challenge, willing to go to so many extremities to kill Chara next time.

When she finds herself reset, she goes on the hunt for Chara, unaware that the child is actually a girl called Frisk this time. At first, she sets out to kill the child, but once she defeats Undyne the first time and gives her mercy, she decides to let Frisk live.

Later, Papyrus decides to invite Frisk to make spaghetti with them, and it turns out into an insanely awkward cooking lesson, ending up in Undyne's house catching fire.

Later on, Undyne finds herself at the risk of death again, Papyrus right by her side this time. As she feels her soul slip away from her, she wants to tell Papyrus about the feelings she developed for him before it's too late...but she's worried it just might be.

(Author note: The start of the story is in the genocide route, while it ends in the pacifist route. None of the artwork belongs to me, but seriously, Undyne and Papyrus are my OTP. I hope you enjoy the story!)
