Thank you to @superdopeygirl03 for the wonderful idea! This idea has two different xreaders that come out of it. One for George and one for Biff. 

Your POV 

I was walking down the hall after school was over. Sighing gently as I saw the Enchantment Under The Sea Dance poster. I shook my head as I went to my locker and grabbed the rest of my stuff before I started my walk home. It never took me very long to get home after school, but today I decided to take the long way home. 

I jumped a little as two boys ran over to me. They shoved each other a little on the way over as I looked between the two. George McFly and Biff Tannen. The smartest and the most intimidating guys at school. But what did they want with me? 

"(y/n)! I have something I want to ask you" George said as Biff pulled him behind him before he stepped closer to me. 

"Beat it shrimp, she has to answer my question first." he said as he smiled down at me. "Will you be my girl-" He fumbled a little as George used his full weight to shove him over. 

"No! Will you go to the dance-" he was cut off as Biff pushed him a little. They stared at each other as I looked at them. 

"What is going on?" I asked as I looked at the two. It would have appeared to me that they both had feelings for me and wanted to ask me to the dance or to be their significant other. I felt my cheeks burn gently as I was flattered over the thought but two boys fighting over me? That was unheard of. Something that would probably never happen in any other timeline. I had to be asleep. 

They looked to me as I had moved a bit back from the boys. They smiled at me as I looked at them. They let each other go as their shirts were now stretched and ruffled out a little. I rubbed my face a bit as I looked at the two before I shook my head and started to walk off. What was I to do? I had never been in this situation before and I wasn't sure what to do. I decided to walk home quickly, forgetting about how I had wanted to take the long way home before those two showed up. 

I got to my room and threw my books onto my bed as I sighed deeply. I paced my room which was something that was normal behavior for me when I was stressed. They were both cute sure but did I like either of them? 

I sat down and looked at the ceiling as I laid there for a moment. I decided that I was going to finish what little homework I had before I went to bed. Sleeping on the decision would be better than being too hasty. I fell asleep shortly since being well rested for a decision is better. 

-The next morning- 

I got up with a jolt before I realized that I would have had to make a rather life-altering decision that day. Do I choose Biff Tannen or George McFly? A question that would cloud my thoughts for the day as I got ready. After grabbing my stuff I made my way to the high school. I sighed as I got inside before I was approached by none other than George. I smiled to him warmly before we heard Biff's voice. We turned around and George went to step closer to him before Biff took a swing. I gasped a little as I looked at the two boys. 

They duked it out in the hallway before Mr. Strickland and another teacher pulled them apart. They were dragged off to the principal's office and most likely got detention for the week. I sighed gently as a couple girls had asked me about what had happened. I shook my head gently as I didn't want to talk about it. Sitting down in my desk the bell rang and we were ready to start the day. But I felt bad about what happened in the hall. Something like that should never happen over someone like me. 

I shook my head as I decided who I would pick. I decided to hang around after school as I went into the detention room. I looked around to see George and Biff. They were sitting on opposite sides of the class as they looked at their desks. Both of them had a fat lip. I sighed gently as I walked inside. I glanced over to Biff before I walked over to George. I was careful not to make my presence known to Biff. I tapped George's shoulder as I looked up to me before I covered his mouth with my hand and moved a finger in front of my lips as he nodded. 

I slipped a note into his hand before I left the room. I waited by the door to hear him exclaim something that I couldn't really make out. I sighed gently as I walked off. A smile on my face as I now had a date to the dance. Saturday was going to be fun even though Biff would probably be sore with me for a little while after this. Knowing him he would probably find another girl to drool over in a week or so.
