Your pov
You were walking in the WaterFall section as you were talking to Monster Kid or MK for short.

He was rambling about Undyne and saying how great she was. She did sound amazing and you wondered if she was amazing as she sounded. You both said good bye as you were heading back to Sans and Paps house. You go inside and find to see Sans talking to Papyrus.

"Heya!" I say.

"Heya kid," Sans says.

"HELLO HUMAN," Papyrus says with a smile.

"So what are ya guys up too?" I say as I walk closer.

"Nothin much," Sans says. I could have sworn I saw him blush a bit.

"Well I was wondering if you wanted to come and take a walk with me around the Waterfall," I said with the geeky smile on my face.

"SURE HUMAN, ME AND SANS WOULD LOVE TO COME," Papyrus yelled.

"Yeah sure kid...'' Sans says while blushing.

"Great! Lets go!'' I say and walk out.

Sans's pov

Yes!! My beautiful rose is going to be with me and only me after this plan I pull. She doesn't know this but once I kill Papyrus, she will belong to me and only me~ I ask Papyrus to come to my room real quick and he follows me.

"WHAT DID YOU NEED BROTHER?" he asks with his idiotic smile. I grab him by the scarf and make him look at me.

"Listen bro...if you ever try to have Y/N as your girlfriend, you will regret it," I say with a dark tone.

Papyrus's pov

he had no pupils in his eyes and it was starting to scare me...a lot. Why is my brother like this all of the sudden. well ever since the human fell, Sans has been acting weird and clingy to her.

"D O Y O U U N D E R S T A N D?!" he says.

"Y-yes!" I stutter. He turns back to normal and has his grin on his face.

"Great..." he says and walks out to catch up to Y/N. I follow from behind. I just need to tell the human this before she gets hurt!!

Well writing this in school is risky...MORE CHAPTERS TO COME!!!
