Look, this is Cas's version but Dean, Sam and the other dudes have their own versions. Yeah okay continue.
Plot: Castiel loved you before but you went to hell and became a demon.
Your POV
I fluttered my eyes open turning them black to show the proudness of me being a demon. I flashed them then returned to my (y/e/c) eyes. I stood up and grabbed my demon blade and walked out the door. I ran to the back alley and flashed myself to an empty bathroom in Gas N' Sip. I pushed the door open and walked out walking to the counter. "Hey," I winked at the guy and flashed my eyes black. His screamed in terror as I slid on the counter and into the small space. I walked forward to the boy who backed himself up until there was no more space. I looked up at him and traced my fingers over his chest. "What do you need? Take everything!" He pleaded his eyes watering. "Oh nothing, just your blood," I grinned innocently at him as he stuttered and pulled his sleeve up. "Wait, so here's the thing... I kill you if you say about this to the cops or if you will call them, or I take your blood and all is good," I said taking my blade and waving it in the air. He nodded frantically and I snapped the goblet in the counter. I grabbed it fast and cut the boy's arm slightly. He winced and hissed as blood dripped down to the cup. "Don't be a wimp," I said as the blood in the cup was enough for me to make a call and grabbed a towel from his jeans and pressing it on the wound. I pushed myself off of him and chanted, swirling the blood a little. I called Crowley but no one was answering. I grunted and threw the cup down making it tink. "Damnit!" I said kicking the goblet away with blood on my shoes. I sighed and snapped the goblet and spilled blood clean and out. "Don't tell this to anyone," I said looking over him and snapping myself back to my room. I sighed as I saw that I was in my room. I kicked the end of the bed as I heard wings flap. I turned around slowly to see a man with a trenchcoat, long haired man and green eyes. I squinted to the man in the trenchcoat to see that he was an angel. "What do you need?" I gritted. I didn't have the best relationship with angels but I got enough, not bad, not good. "(Y/n)?" Trenchcoat said with him getting sad. I twisted my head to remind me of Castiel. "Castiel," I whispered lighting up and furrowing my eyebrows evilly. I smirked as I flashed my eyes black. I flashed them back, smiling and throwing me head back. I breathed out and smirked at Castiel. "(Y/n)? What- what happened?!" He said tearing up and walking towards me. I backed up until I hit the bedside table. He placed a hand on my cheek as I slapped it away. "Don't you dare touch me," I said walking past him and snapping away. I ended in an alleyway as I kicked the brick wall screaming angrily. I punched the wall and there was a little indent. "(Y/n)," I heard Castiel's same voice calling me. I turned around angrily to see his face filled with every sad and depressed emotion. "I'm so so sorry," he pleaded as a tear fell down his cheek.
Flashback:
"Promise you'll be back?"
"I promise," he said as he disappeared. I turned around and continued cooking the soup for our dinner. Once I was done I placed it on the bowls and waited for Castiel to come back.
But he never did.
That night I cried myself to sleep ignoring the howls of the neighborhood dogs. Once I had enough of me being all sad, I grabbed a demon box and ran to the crossroads fairly far from the village. I kicked the rocks away and dropped the box in the small pit. I kicked the rocks back and chanted the Latin words. I turned around to see a well dressed man with red eyes swirling to their green ones. His light brown hair slightly ruffled and his glasses framed his face. He smiled as he walked around me. "What can I do for you?" He smiled rather kindly than harsh. "Make me a demon,"
I looked at him harshly as his eyes filled with pity and sadness.
"(Y/n)?"
"Castiel you left me,"
"I know and I'm-,"
"No Castiel! You're not! I waited for you! Centuries Castiel! And all is sorry? Is it time to play hide and seek now?! What did I ever do to you for you to leave me?!"
"To keep you safe,"
"Look how that turned out. This is the problem, Castiel, you didn't and will never understand humans,"
"(Y/n)! Listen! I am so sorry! Zachariah threatened to kill you and me if we stay together. I couldn't do that,"
"Death is adjacent to demonology, Castiel. It's better if I died so I didn't become a demon and die all over again the next day," I said sternly as he began to whimper. My chest deepened as he began sobbing quietly. His whimpers became louder and so did his sobs and sniffles. I turned around and furrowed my eyebrows. I kicked a rock and grunted. "Damnit!" I yelled as I ran to Castiel wrapping my hands around him. I lifted him up, lighting his face as his whimpers softened. "I'm so sorry," he kept repeating stroking my hair and sobbing on my neck. "Sssshhh," I said with tears brimming my eyes and stroking his black hair. I blinked mine as tears fell down his hair and I hugged him tight. But I pulled away once his sobs stopped. "But you know we can't be together again right? I have a trace of hell everywhere while you have the record of heaven," I said cupping his cheeks as tears fell down again. I wiped them with my thumb as I smiled sadly up at him. "We can try please (y/n), come back," he whimpered with his tears coming back. I looked away and shrugged. "It's my time to keep you safe," I said softly kissing his lips gently and pulling away. He opened his eyes and realized I was not there anymore...
