E/C means Eye Color

Ink's P.O.V.:

   'Oh Y/N, My Little Butterfly~ Why would you choose Error over me? I am clearly the better choice so... AM I NOT GOOD ENOUGH FOR YOU?! IS THAT IT?! I guess I'll have to get rid of Error then. Then you shall notice me and know my true intentions towards you, my love~' I thought to myself while looking at Y/N and Error hugging and cuddling  in the Anti-void. That should be me not that piece of shit. I had already killed Blue and Dream for having an small crush on my Butterfly but I guess I have forgotten about Error.

   I looked at my paintbrush, remembering when I had created Y/N. I made her so I could have someone to love me but I guess it backfired since she ended up liking someone else. I need to wait until my Butterfly is asleep so I can put an end to Error's worthless life.

Y/N's P.O.V.:

   I was cuddling with my boyfriend, Error, but I couldn't shake the  feeling of being watched out of my head. I decided too ignore it and continued to cuddle with Error. Yes, he does have Haphephobia but he was okay with me touching him. "H3y Y/N?" I heard Error's glitchy voice say. "I w0rRy ab0ut Blu3. W3 h4v3n't seen h1m in a l0ng t1me." "He's probably fine. If you want, we could go visit him!" I said, hoping too make Error cheer up. "Sur3! I'll 0p3n a p0rt4l t0 Und3rsw4p r1ght n0w!" Error exclaimed as he had created a portal. 

   Then we jumped in as we landed in skele-bros' house but then we saw U.S. Paps, crying on the floor. I ran over to him, kneeling down beside him and immediately asked him while putting a hand on his back," Paps! What's wrong?! What happened?!" "S-sans was ki-killed!"He spoke hoarsely as I then hugged him to my chest, tears starting to stream down my face. He cried into my shoulder and all I could do was try to comfort him as I was seemingly trapped in a daze. "I d1dn't d0 1t...Blu3 i5 mY f413nD 4nd 1 sw34r I'lL f1nd wh0 k1lLed h1m and r3tu4n th3 f4v0r t0 th4t b1tch!" Error said pissed, his voice glitching out more than usual. I calmed him down and sat down with U.S. Paps, talking to him, hoping to make him feel better.

~Time skip~

Error's P.O.V.: 

   We were back at the Anti-Void and Y/N had fallen asleep in my arms. I pet her hair and sighed, still pissed. "WhY w0uld s0m3oNe w4nt t0 kiLl Blu3?" I questioned myself, mumbling to where it was almost inaudible. Out of nowhere, I heard the sound of someone falling and land on the ground. I gently laid Y/N down, making sure she wasn't awaken by my movements, and went to investigate the sound.

   When I got there, I realized that it was Ink but he was covered in something that I couldn't quite make out. As I got closer, I soon realized that he was covered inn blood and monsters dust. I'll admit, I was disgusted by it and thought Ink would never stoop that low to prove a point to me. Even I wouldn't do that. I summoned my blue strings but was hit behind my skull before I could do anything, knocking me out cold.

~Small tiny time skip~

   I woke up being tied to a chair. I tried using my strings but my magic seemed to be disabled. "Seems like you finally woke up~" I heard someone say from the darkness. The thing was, I know that voice from somewhere, but my mind was too blurry to comprehend who it was. Then an all too familiar skeleton figure emerged from darkness that surrounded us both. Ink. He was holding a sharp blood covered knife that glinted in the only source of light that hung above my head. Blood dripped from the blade, making me gag at the thought of who's blood it is.

   I started to breath heavily as I thought,' What was gonna do do with that and if Y/N is safe?'. Ink started to walk closer to me and held the knife to my fingers. My hands were tied down so I couldn't move an inch away from it. "I'm only doing this because you tried to take my Butterfly from me~" Ink said, his voice had insanity engraved in it, and I soon felt my fingers be chopped off, one by one. It hurt like fucking hell. 

   I screamed and thrashed about but it was of no use. Then once he chopped off my hands, he started to cut off my ribs one by one, enjoying my screams of plea for him to stop. Every one that was cut off, an extreme wave of pain crashed and went throughout my entire body, only getting worse with every one that was touched.

   "P-pl34se s-st0p!" I yelled, hoping he would stop. He did for a moment before he said, "No~" as he then stabbed me in my neck, blood gushing from the wound with my vision going black. My last thought was of Y/N smiling and laughing because of something I messed up on. She giggled as I huffed and got frustrated but she kissed my cheekbone and wrapped her arms my neck, making me smile back as my attempts to look mad failed at trying to make a pie. She was teaching me how to cook and I was failing miserably. I heard her say my name and her saying that she loved me as I said it back, kissing her on the lips, making us both smile. I smiled at seeing her and hearing her voice one last time as I took my final breathe.

Ink's P.O.V.: 

   I stabbed Error in the neck, causing him to slowly turn to dust. Before he faded away, I saw him smile over something but I shook it off, thinking of Y/N. Once he was completely dusted, leaving behind his navy blue scarf, I smiled and teleported to My Little Butterfly and found that she was still asleep. I picked her up and teleported us to my basement. I then tied her to the chair Error was in and waited for her to awake from her peaceful slumber.

~Time skip bc I'm laaazy~

   Once My Little Butterfly had awoken, I saw her beautiful e/c fill with terror and fear. She looked completely horrified. "My Little Butterfly! You're up!" I said happily and with a hint of insanity hidden in it, "I've been waiting for awhile for you to awake!" "I-ink?! Wh-where am I?! Wh-what's going o-on?!" She asked with complete fear in her voice, breathed heavily. "I love you, Y/N, and I brought you here so you would finally be mine and mine alone. It's why I killed Blue, Dream, and of course Error. They were all trying to TAKE YOU AWAY FROM ME!" I yelled, and getting her to look up at me with shock and sadness written all over face as she turned pale. Then, I saw her gorgeous eyes tearing up and tears started to stream rivers down her soft smooth skin.

   Oh no! What have I done? Well, it doesn't really matter anymore since she's now mine forever~
