~~~Your POV~~~
-(Dreaming)-
My eyes opened as I saw where I was. The exit of the Ruins. My face was completely blank. I looked at my hands, blood and dust covered them. My hand holding a toy knife. I sighed, I knew what was going on.

I started walking.

Then I heard it, a window opened, but I still kept walking.

Then they appeared. The strings. They tied around me amd started pulling me into the window. My eyes widened as I entered a completely white void. I turned to see my capture. Sans, but not sans. No this was Error sans. Not that I knew at the time.

"W-w-well who-o d-do we h-h-have he-ere?" Error asked, strings tied around my soul now. My soul was Green but with cracks and red spilling from those cracks. "S-s-seems li-ike your-r al-lmost insan-ne." He said cheerfully.

My eyes started leaking tears but my face was completely blank. I just stared at him.

"I-i-i can-n fi-ix that y-y-y'kno-ow? But-t co-omes with a-a-a pri-ice." He released his strings. "N-n-now sho-ow me-e how-w m-much y-you want i-i-it!"

I smiled and started laughing crazily
As tears rolled down my cheek. I took no time at all. I stabbed where he was, he dodged. "C-come o-on, y-you can-n do-o bet-tter than-n t-that right~?" He cooed. I stabbed
Where he was again. He dodged.

He picked me up with his strings and flung me across the void. I rolled and jumped as bones shot up from the ground. I skidded and tried to stab again, again he dodged. He summoned his gaster blaster and shot while throwing some bones. I dodged narrowly. I stabbed again, missing.

I started getting slightly frustrated, and frowned. "He-eheh-h, I-i can se-ee your-r true f-f-face now-w." He said with a glitchy laugh, it confused me, but for a second. We started fighting again. He threw me, shot at me, and tried to impale me. I kept trying to stab him.

Hours passed, I was starting to tire out and he noticed once he finally hit me my health dropped to 12/28. "What-t tir-r-ring out al-already?" I glared at him, and tried to strike at him, but he stopped me midswing with his strings.

Blood dripped as the strings held tightly and he said, "To-o-o tell y-you the-e tru-uth I don't-t know w-what you a-are. You're-re not a-a-a dirty glitch-h or an o-o-original. You're mo-ore l-like an an-n-nomaly, but I-i-i don't w-want to kill-l you u-u-unless I-i have to-o. So l-let me he-elp you instead-ad, b-but you ha-ave t-t-to help me i-in retu-urn... So d-d-do we have-e a-a deal-l?" he asked, his strings released me and he held his hand out. I stood there and stared at him. My crazy smile faltered. I took his hand and shook.

I felt tears running down my face as i looked up at him, smiling genuinly now. "Thank you." I said dropping the knife and hugging him, sobbing. He flinched and was tense for a bit before hugging back after a while.

I finally let go , calming down, and looked at him with puffy eyes as asked, "How can you help me?" He looked at me and smiled.

"W-well you're-re going to-o h-have to fu-use w-with a diff-ifferent soul-l-l first." He said with seriousness and pulled out a container with a purple floating in it. I gave him a confused look. "T-t-this is a-a soul o-of pers-serveran-ance. It w-w-will help with-h the insan-nity." I nodded. "Once you-u-u fuse w-with it i'm go-going to tie y-your soul-l aro-ound i-it with m-my strings-s to-to keep t-t-the souls tog-gether-r, o-okay?"

I nodded. "I'm ready." He nodded and opened the container. "N-now put yoo-o-ur s-soul next-xt to-o it-t, this-is w-will hu-urt for a-a-a bi-it." I quickly released my soul and put it with the purple soul. A sharp pain went through my body. The heart almost shot out until Errors strings tied around my soul, locking the purple heart in place.

I trembled, I fell to my knees as pain surged through my body, My breathing hitched, as I started gasping for air, which soon turned into hyperventilation. Sweat dripped down my forehead. My body was shaking and soon I started crying. Then I started laughing. I heard error from behind me say, "T-the insan-anity-y i-is try-ying to get t-t-to yo-ou, you n-n-need to calm-m d-down."

I tried taking his advice and stopped the laughing forcibly. Giggling I took deep breathes. I stopped giggling and my trembling slowed. I continued breathing deeply. After a few minutes my pulse went back to normal along with my breathing. I pulled out my soul and saw all the cracks and red were gone but were replaced with blue
Strings holding the purple soul around my green one. A tear fell down.

"It's pretty." I whispered. I felt a hand go on my shoulder and I rose standing up. "So what do you need me to do?" I asked.

"W-well..." He said.

Then I woke up.
-(End Dream)-

I got up slowly and looked around to where I was. I was in sans' room. I got up off the the bed and headed out the door. The house was dead quiet. I walked downstairs and looked into the kitchen.

There was sans and Pap both with sad faces, both staring at the table. A bottle of ketchup was in sans' hand. I leaned on the door frame. "Who died?" I said scaring both of them. They looked in my direction and both of their eyes widened.

"SEVEN!!" They both yelled and hugged me tightly.
"Can't...... Breath!" I choked out and they loosened and looked at me. They were both crying. "What's wrong?" I asked.
"Kid.. You were asleep for a week. We thought you wouldn't wake up." sans said. Blue tears streaming down his face.
