I woke up, groaning. I had a massive headache, and everything hurt. "Never let me drink again..."

"Don't be so sure you won't."

My eyes widened and I shot up in bed. My eyes quickly adjusted, seeing a blonde guy sitting at the edge of the bed. He smiled, his mouth full of sharp teeth. "Good morning, (insert your gravity falls symbol)," he said softly. His voice seemed familiar...

Then I realized. "You were the mysterious figure outside my window! Why the hell are you here-?!" He shut me up, covering my mouth with a gloved hand. "Shhh, you're gonna wake the whole town." I quieted down instantly. He let out a sigh, pulling his hand away from my face. "Who are you, anyway...?" I inquired hesitantly. He flashed a smile at me. "My name is...."

"Bill?! As in, Bill Cipher?!" My brace-mouthed friend screeched into my ears. "Mabel, chill! What the fuck is wrong with you?! It's nine in the morning!" I whisper-yelled. "Sorry.... It's just, me and bro-bro have dealt with him. And believe me, it was not at all a fun experience." What did he do to them...? 

"Hang up the phone," he muttered. I growled at him. "Fuck off," I hissed. He rolled his eyes. Mabel, however, heard that. "He's there with you right now?! (Y/N), what the hell?!" she screamed. "Yes. Here, have a chat." I tossed my phone at him, and he caught it with surprise. "You have some explaining to do with my friend." He groaned, and held the phone up to his ear, immediately being taken off guard by Mabel's loud angry yelling. "Thanks for the warm welcome, Shooting Star." I could overhear their conversation due to her yelling. I'm pretty sure she went to get Dipper at some point, too. And Bill was greeted with more yelling. "Wow, you carry after your sister, Pine Tree. I didn't know that was shared with the twin thing," he joked, earning more frustrated talking. I sighed and waited a few more minutes before I took my phone back. He had basically explained, so I didn't have to worry about that. "Okay, enough of him," I muttered. "Don't make a contract with him," the twins said in almost perfect unison, then burst into laughter. I smiled as well. "I won't, chill."

After about ten minutes more, I hung up. "Oh, Bill, whatever will I do with you?" He just shrugged and smiled. I had to admit, he was kinda... hot. I shook my head, stopping my thoughts. He was staring at me, trying to figure me out. I shuddered, I felt like he was trying to stare into my soul. "I'm not, just so you know," he muttered. My eyes widened. "How- what- why- Huh?!" I kept tripping over my words, confused. "Y'know, I am a dream demon. I can invade the mind." I shuddered at the thought of him being able to see my  fantasies.  "Ew, no." I was getting annoyed with this little bastard.

And then we went shopping. Yay shopping. Yaaaaaayyyyyyyy. Haha, no. I hated shopping. But I was running out of food, and the annoying little demon insisted on getting clothes. Thank God I was semi-rich. After what seemed like an eternity, we got back. I guess that since Cipher showed up at my house, he basically lived with me. Oh boy! How diddley darn fun! Not.

"Alright. Bill, let's lay down some ground rules. No going into my room, no setting the house on fire, no trying to take over my mind, no trying to get into my dreams, and no touching me." 

"But (y/n)-channnnnnnnnnnnnnnnnnn~"

"No," I said firmly. "Fine. Can we shake on it?" he asked. "Ye- wait. No. Don't try to pull your contract shit on me." He raised his hands in defeat. "Fine, fine, you caught me."

I showed him to his room, then we had something to eat. It was getting dark out, and I was exhausted. I sighed and sat down in front of the T.V, watching a movie. I got about thirty minutes into it, before passing out.

And almost the same exact thing happened.

I woke up the next morning, yet again in my bed with no clue how I got there. But now I had more of an idea how.

I sighed, walking downstairs to be pleasantly surprised by the smell of eggs. "Morning, sleepyhead. I made some breakfast," Bill said from the kitchen. "You know how to cook?" I asked, surprised. "Of course. How would I have survived if I didn't?" he said with a smile. I shrugged, and he put a plate down in front of me. I might have to get used to this....
