~The Promise~

(A/N: This might be emotional or OK with some of you)

Your P.O.V

"Hmmm..... wait.... THIS IS LIKE THE ONE FROM BEFORE!?!" I thought mentally screaming in my head I walked to the opened door way but it's really different from the other one it's snowing? "HOW DOES THAT EVEN WORKED?!?" I thought I looked at the bushes and saw a red thing? I looked closer it's a.... camera?! I sighed

"Maybe this is gonna be a long journey." I said to myself I looked at Flowey and he was still sleeping.

I started walking and saw a branch I decided to walk through it because why not?

I walked straight forward and heard a 'CRACK' noise I looked at the branch and it was broken "nope!!. nope!!. nope!!" I said to myself and walked faster. 

Then I heard loud footsteps I decided to run and stopped at a small bridge to catch my breath "Man.. *huff*... I wish.....*huff*.... I slept... longer..." I said just then Flowey woke up and looked at me worriedly.

"Y/N WHAT HAPPENED TO YOU!?!?" Flowey said panicking.

 I tried telling him but a tall figure was behind me "H u m a n..." The figure said I froze in my place.

"D o n t Y o u K n o w H o w T o G r e e t A N e w P a l ? T u r n A r o u n d A n d S h a k e M y H a n d" The figure said I turned around and shake his hand it zapped both Me and Flowey after that we just stared at the laughing skeleton. 

"Hahahaha!!! This thing is always hilarious!!!" He said through laughter.

"Hey kid you better watch where you going or you'll end up dead where you stand!" The skeleton said and disappeared like he was never there.

"Wow he can teleport....." I said Flowey looked at me confused.

I decided to walk through the small bridge luckily I still have my bag with all my things in it.

I put Flowey to the ground and start practicing my magic first he looked at me confused.

"I really have to explain this to him huh?" I thought.

"Flowey can I tell you somethin'?" I said he nodded his head 'yes'

"Ok here goes nothing.... My brother Blake found a monster DNA at the place were the war began, he wanted to test his theory about combining a human DNA and a monster DNA but no one wants to be his test subject so I decided to be one, he was really obsessed with it and always forgets to feed me or forgetting that I existed, everyday he only checks me not for my health but my magic, his not the brother that I used to know his a twisted madman that only cared for his inventions, I never had any friends though so that means your my very first friend and it feels really.... Good to have a friend." I said he let a single tear fall off his eyes and hugged me using his vines.

"I never thought that the happiest person that's always smiles to every monsters she met had the worst twisted past on her own.... But why are you always smiling and spared all the monsters here? All monsters here are the complete opposite of you but why are you still determined to make them your friends?" Flowey asked.

"Because.... I believe that every monsters deserve a second chance not because they're rude and always kill their fellow monsters but I believe that there's still good in their souls and I'm determined to save them all even it means losing my own life...." I said honestly then we broke the hug.

"Do y-you really mean that?" Flowey said.

"Yes!" I said smiling happily as I began to summon a small Gaster Blaster.

I always started it small so I can save some of my energy for someone in need or in danger I tried to make a small blast but it went wrong the blast was really huge I decided to use my magic to fix it and it did some monsters are heading on our way so I grabbed Flowey and teleported to I don't know?!? 

When we landed we are in a Waterfall well... Inside the Waterfall it was like a cave but with blue flowers.

You heard a passing conversation:

Hey what's up?

Nothing much....

Awww come on you can tell me anything!

I had a dream....

What's your dream then?

My dream was we were above the ground with humans and monsters living happily with each other we were happy there and were always smiling ..... But it's only a dream.... The world of monsters and humans will never be like my dream....

Your dream will become true someday.

Promise?

Promise now come on before dad finds out were here. 

*laughing happily*

"I promise to make your dream come true little one...." I said quietly so Flowey couldn't hear it.
