Just a few tips. Make sure you space out your dialogue like this:
"Bella?.. Bella!" Louis shouted.
"What!?" I shouted, tired.
"Get up!"
"No leave me alone," I hissed.
I pulled my blanket over my head. Just as I got comfortable again, my blanket started to move. I sat up to get a good grip on my blanket.
"You're not going to win this," Louis said.
"Bring it," I smirked.
Notice how I corrected some of your small errors. (: Also with the spacing. With that, I know you're on mobile so it's a bit hard to catch those minors. Just make sure you reread it and proofread. :)
Over all, I like the storyline it's heading to. And, thank you for the credit! I hope to see more! :D
