HE IS MINE!!!

A/n: In this fan fiction, the White Fang does not exist! So Em, Cinder and Merc is not evil! Kay? Lets go!

====================

Dear diary!

I was watching students at Beacon Academy. I wasn't a student there, I was a citizen in Vale. Then I saw him! His gray hair, silvery eyes, beautiful smile. This moment changed my life for good. I knew he was the one! My senpai!

I saw him walking down the street with his friend. "H-Hi." I jumped in front of him. "M-My name is Y-Y/n." I stuttered. "Hi! I'm Mercury. This is my friend, Emerald." He smiled at me. "Hi." The girl named 'Emerald' waved. I ran away to my secret hideout. "Well that was weird." I heard him say.

When I reached my hideout, I said to myself. "Mercury? That's his name." I smirked. "Sorry, Merc. But your little friend will have to die!"

~•The next day•~

I watched the students at Beacon as usual, but this time the feelings were different. "I need him!" I whispered to myself. After they're school time was over, I invited Mercury and Emerald to my little hideout. "Thanks for inviting us!" Emrald smiled. "No problem. Emerald, come here! I gotta show you something." I stood up. "Okay!" Me and Emerald was walking deeper and deeper into the forest. "So, where are we going?" Emerald asked. I stoped. Pulled out a katana I that I had hid under some rocks the day before. "What are you doing...?" Emerald said nervous. "Those will be your last words... HE IS MINE!!!" I shouted as I murdered her. She let out a loud scream. I hid the katana that was full of blood under the rocks again. I used my semblance to create a fake grimm with bloody claws. Mercury heard the scream and came running. "What happened?!" He shouted. I was fake crying. "She... She got killed by a grimm! I tried to help but the grimm was too fast and too strong!" I lied as fake tears streamed down my chin. "No... It can't be! NOO!" Mercury was horrified. Tears streamed down his face non stop. He got up and killed the grimm in one hit, screaming.

~•The next day•~

I watch as Beacon held a funeral for Emerald. No one had any idea that I was behind her death.

~•Later that day•~

"Hey, Merc?" One of his friend said. "Where you there when Em died?" "No, but one of my friends where there." He answered. "Who?" The guy asked. "A girl named y/n." "Maybe she's behind the attack?!" He said. "No, it was a grimm!"
*Bell rings*
(I'm too lazy to write the conversation. Sorry)

So I watch trough the window. They were having a practise fight. I saw Mercury. He was going to fight another student named... Pyrrha Nikos, or somthing. (Since the White Fang don't exist, Pyrrha is still alive. And the fall of Beacon never happened.) The girl attacked senpai. That made me really, really, really mad! I burst trough the window! Attacking and killing everyone! The teachers tried to stop me, but I killed them! "Y-Y/n!? What are you doing?!" Mercury was shaking in fear. "I'm protecting you, dear senpai!" I responded. "Hahahahahahahaha!! I was the one who killed your dear Emerald!" I laughed. "H-HOW COULD YOU!?" He ran as fast he could. "You can't escape!" I grabbed his arm. "N-No. P-Please no!" He stuttered. I grabbed the back of his neck and kissed him.

Aaaaaannd the story's over!
