FRISK P.O.V
It felt...so painful...I felt like I couldn't be alive anymore. I keep seeing the light but I can't leave! My breathes breath heavily and I can feel sans is trying to hurry himself as fast as he can. I felt so scared...and I felt like someone is taking me away. I decided to try to hold on no matter what....for sans.

I see that Flowey still had tears in his eyes, "please frisk..hold on.." I kept hearing that repeatedly. I was so scared...am I gunna die? Or am I gunna live...does it matter? All these thoughts running in my head. I was feeling scared but glad to have someone around me like they always loved me.

"Keep holding on please..." I kept hearing someone saying that. I felt so confused but I put my warm smile to it, I felt memories coming though me making me feel happy. I saw memories that me and sans been doing together, memories that I've done for everyone...everyone I even love. Sans was panicking so much I tried to calm him down...but I can't say a word to my mouth.

I felt a bit quiet...I wanted to tell sans so I did, "San...p..pl...please...H...hurry..." Sans took the speed and went on faster. I felt like I was levitating but not carried it seems sans has been really tired from his magic and decided to carry me with his own warm boney arms. "Please stay with me sweetheart we're almost there.." I felt a bit of tears on me but I mostly thought it was Flowey.

I tried to make Flowey better, "don't worry...I..will..try...to...hold...on.." I felt like o could still talk but I wanted to save it before it gets any worst. Sans went faster and I saw a light...is that? What I think it is? I heard sans feeling a bit stuffy, "we're here sweetheart. " I felt so...scared. I don't know...if I could even make it...I felt like memories are coming towards my head hurting me. Memories flash them back and forth making me dizzy and more dizzier, "don't worry keep holding on" I felt afraid who is there? "I am the inner thoughts helping you..." I couldn't think till, "sweetheart please stay awake!" Sans started to calm down but was a little worried.

I started to talk and well I remember what I said very much, I felt like this was the end mostly...I felt sorry and more memories flash...the day me and sans hang out...the day we met...the day he says beauty of words to me...the times we comfort me...all these things made me smile, "always be kind..." This was it...I was ready to leave...

SANS P.O.V
*sigh* I felt scared and afraid that my nightmare came true...frisk...she can't die yet. We arrived at the place I tried my best to hurry her, "sans you gotta get the souls to free all of us and frisk!" Flowey said. I started to grab the souls and nothing worked, "what the hell?!?" I felt so confused it was it right?!? "Wait..." I counted the souls SHIT! There are only 6 souls... I felt so upset! I knew this wouldn't work as much as I thought it would work.

I was so angry frisk spoken to hush me, "seven...seven....souls..." I was shocked at this point, "sweetheart...no ple-" I was cut off by her soft voice, "p..please....free....everyone.." At this point I couldn't help it anymore this was the first time I would ever cry in years...I thought I could handle this kind of stuff...but I was wrong...frisk is the thing I was missing the most...she was the puzzle piece to everything that ever reminded me that I ever love. I saw frisk shocked that tears Flowed though her face and it made me wanted to scream.

Frisk soul came out...it looked so hurt and so red...I couldn't bare to take it...for she will die so I melt refusing and I felt afraid that it would be my fault for killing the one I loved by taking her beauty of her soul..

"Sans...won't you...smile...for me..."

"Sweetheart I..."

"P...please...can't....last...any...longer..."

I grabbed my sweethearts hand...and put it towards my cheek...

"I'm.....
         *flash back* ("Wanna come?")

"Smiling..."
     *flash back* (be rude? Huh I don't want to)

"Sweetheart..."

"Sans....I...~~~~ ~~~"

"I...didn't..."

"Quiet catch that..."

"Can...you...please.."

"Say...that again..."

"Sweetheart?"

After that...I saw nothing but mid air...she disappeared. There was a flower sitting there...alone...I picked it up slowly and felt the warm of the appearance of frisk. "Sweetheart...", "don't worry sans...ill come back" I felt a bit relief but...I don't know how to feel about it anymore. Flowey wrapped around me and we both walked slowly. I grabbed an old pot and put the beauty of the flower...then the gate opened...I saw the light of our way.

I went towards it...and she was right about the surface...it was full of beauty...especially the sky...even the stars glaze towards my eye sockets, "sweetheart....I will...do...my best...to...wait for....you.." I sat at the Rock cliff and gaze the sky that was the beauty of the color of blue, purple, and black. I saw a shooting star that made me wish, "I wish you were here sweetheart.." I felt someone hugging me behind me, "don't worry...I'm here...but you have to wait...always be kind.." Frisk appearance disappears which made me sob and cry..."I love you...sweetheart.."
