ENJOY! In this I imagine them both as five year olds. I'm adding Error's older sister as well.

Ghoul's POV
I sniffed as I wiped my tears. My daddy didn't come here to get me. My mommy isn't here she passed I think that's what daddy told me. But as time went daddy got meaner to me yelling then he left me here all alone at the playground. I decided to make the best of my problem and calmed down then went onto the playground. I went on the slides a few times then I saw a girl my age sitting on one of the lonely slides. I tapped her shoulder she turned around quickly. When I looked at her I noticed she had cat ears and a cat tail, had a green streak of hair in the front barely covering her left eye so I could see it perfectly. "Yes?" ahe asked me. "I-im sorry! I didn't mean to disturb you I was wondering if you were all alone." I asked while blushing a light pink. The girl smiled at me and shook her head. "No big sissy is here with me just over there" she said and pointed towards a girl who looked almost like a big girl but still older than us. She smiled and stuck her hand out to me.
"My name is Error! What's yours?" Error asked. I smiled and blushed still and shook her hand. "My name is Ghoul! It's nice to meet you Error!" I said while grinning as I felt my wolf ears and tail twitch. She suddenly hugged me. I squeaked at her actions but hugged back confused. "you are so cute Ghoul!" she says while smiling at me. I blushed badly now I know I was cause I could feel the heat. She giggled at my reaction. "T-thanks" I muttered embarrassed also at the position we were in and I saw no one else was here except us and her big sis. "Hey where is your mom or dad or sibling?" she asked me. I felt tears start to run down my cheeks. She looked sad and regretful then hugs me again. "I'm sorry for asking" she said while frowning a little. I shook my head "I-it's ok mommy isn't she passed, daddy left me here after yelling at me" I said sadly smiling. Error gasped and hugged me tighter. "That doesn't sound nice at all. Hey maybe you can stay with me and sissy" she says hugging me. I smiled and nodded "Can I? Lets go ask your sis then" I said smiling. She grabbed my hand and dragged me (not literally) over to her big sis. "Rue! Meet my new friend Ghoul!" Error says while smiling. Rue looked at Error smiling and messed with Error's hair. "Good job Error nice to meet you Ghoul I'm Rue" she says while smiling at me. I of course smiled back cause I love smiling. Rue picked Error and me up. We of course weren't that heavy. She carried us to their house and I heard a woman's and man's voice talking in the living room. Must be Error and Rue's parents I thought. Error hugged me while Rue carried us to what I thought was a room. It was actually Error's room she set me and Error on the bed. Error immediately hugged me while purring. I blushed at this but hugged back and smiled. "Mine" Error said in some kind of voice I couldn't understand so I shrugged it off. Rue smiled at us and took a picture of us hugging and cuddling. Error giggled at my reaction and I smiled and started to fall asleep. Rue and Error noticed cause Error hugged me a little more. Rue grabbed a book and started to read a bed time story. Error feel asleep​ and I was already passed out. We were hugging each other scared to let the other go something (666) might happen to them. Thus the start of a beautiful relationship that meant more than friends and best friends. They would soon develop love feelings for the other and didn't tell but would blush showing it. They got together after a two years in highschool. Then when they graduated high school they were one of the lucky couples to be able to stay together through the school years. Some time after that Error had proposed to her beautiful girlfriend and she said yes of course. Error was secretly a yandere and had threatened any guys that would flirt with her wife but her wife would reassure her she would never leave for someone else besides her true love. One year after their marriage they had a beautiful baby girl named Angel. Angel had her left eye red like Ghoul's and her right eye green like Error's. Angel grew up to be a beautiful young girl. The married couple never left each others side no matter what. This beautiful relationship started with Ghoul and Error playing at the park and meeting.

This is truly a good and adorable one shot 861 words. That's all.
