A/N: Hello everyone!

Thanks for clicking on this story :D

Today, I am proud to present "Run Devil Run". I was listening to "Run Devil Run" by SNSD, or Girls' Generation (Not the Ke$ha version. It's ok, but I don't think it's as good.), and I thought I'd write this fic. It's kiiinnnndddaaa based off of it...but not really... :)

The characters are a little OC, but I hope ya like it!

Here we go!

DISCLAIMER: I do not own the song "Run Devil Run" or any of the Harry Potter characters. I just own the plotline, which I hope is somewhat original, since I haven't read any stories like it...

You better run, run, run, run, run.
I won't give in, I'll just kick you.
You better run, run, run, run, run.
Even if you beg me not to leave, I don't care anymore.
(Hey) I'll come back even better
and i'll get revenge. Don't forget it.
You better run, run, run, run, run.

"Flitwick assigned so much homework!" complained my boyfriend, Ron. Ron and I had been dating since our for a year now, since we were now in our seventh year.

"Oh come on now, Ronald. It's not that bad." I said, stacking my books up. We were sitting in the library.

"Will you help me with it, 'Mione?" he pleaded, his cute blue eyes looking pitiful.

I rolled my eyes. "If I won't, who will?"

He laughed and kissed me on my cheek. "Thanks."

My face grew red and I stood up. "We'd better get going."

"Go ahead without me. I'll see you tomorrow, 'Mione." he said, winking.

On my way out, I bumped into Pansy Parkinson. She was a seventh year Slytherin with long, brown hair, with a bit of a pug's face.

"Move it, mudblood." she growled.

I just ignored her to the best of my ability and walked out of the library.

I was halfway down the corridor when I suddenly realized I had forgotten my quill. I hurriedly ran back to get it, but stopped short when I heard voices.

"Ronnie, it's been forever since we've been alone! And why are you still dating that mudblood?" came that familiar voice. Who was talking to Ron?

"Sorry, Pansy. But I need SOMEONE to do my homework." replied Ron.

My mouth dropped open. This wasn't real. This wasn't real. Ron was not cheating on me with Pansy. Ron wasn't only dating me so I could do his homework.

"Fine. But dump her as soon as you can." purred Pansy.

"And you dump that ferret, Malfoy. Merlin, why would you go out with him?"

"He's rich." she said. Suddenly, there was silence. I peeked at the two, I dropped all of my books. They were snogging like there was no tomorrow.

"RONALD BILIUS WEASLEY, YOU CHEATING BASTARD!" I screamed. Madam Pince was probably going to kill me, but I was so angry I didn't care.

They broke apart startled, and I had never seen someone's face go so red.

"H-Hermione!" he stuttered. "This isn't what it looks like! H-h-how long have you been there?" he exclaimed.

"Long enough, you two-timing dickhead." I growled, tears starting to well up. "I hope you're happy." I said, and I ran away, tears flowing down my face.

I ran to the deserted Gryffindor commonroom, and cried my heart out. I couldn't believe it. I sat there and sobbed, wishing it was all a dream.

I wiped the tears from my eyes and blew my nose. I would get him back for this, if it was the last thing I do.

The next morning, my sad feelings were gone, and replaced by pure hate. I was going to make him and Pansy suffer. They should keep in mind, there is nothing I do better than revenge.

I walked down to the Great Hall feeling determined. I took a seat next to "Hogwart's Cutest Couple", AKA, Harry Potter and Ginny Weasley.

"Hermione? Are you alright? You look...different." said Harry.

"I'm perfectly fine. Now, do you see Malfoy? I need to talk to him." I said, scanning the Slytherin table.

"Alright, she's insane." said Ginny.

I saw him sitting next to Blaise Zabini, and leapt up. "Sorry, I'll explain later, but I've gotta go." I said, dashing towered the Slytherin table.

"Malfoy!" I hissed. He turned slowly toward me.

Draco Malfoy, no matter how evil or annoying he was, was most certainly hot. His blonde hair, as well as his uniform, was kept messily, which was certainly attractive on him. But I was reminded constantly that he was horrible.

"What do I owe this displeasure, Granger?" he asked, his gray eyes cold. He had stopped calling me a mudblood after I had punched him once in our 3rd year, and another recently, which was good.

"Look. I need to tell you something, can you meet me at the library during your free period? It's 2nd hour, right?" I asked.

"Stalker, aren't you? I bet you know my entire schedule?" he asked.

"Don't be flattered. Your schedule is almost identical to mine, Malfoy." I said.

"What do you want to talk about?" he asked, boredly.

"I'll tell you when you meet me there." I said.

"Ooh, you can't keep me in suspense like that. Alright. I'll see you in the library during second hour." he said. "But this better not be a joke."

"It's anything but one." I sighed.

Second hour arrived, and I stood in the library, waiting. Five minutes later, Malfoy arrived.

"Alright, Granger. This had better be good. I'm giving up my valuable time for this." he said, in a dull expression.

"I could give you a huge, emotion-filled speech, but since all you know is cruelty, I'll save it." I said.

He stiffened. "That's what you think, eh?" he muttered. "Go on."

"Well, long story short, I found your girlfriend snogging my boyfriend last night." I said.

His attitude changed entirely. "You're kidding." he said, flatly.

"Nope. But you don't love Pansy. At least not as much as I loved Ron, so I'm not even sure you care." I said. Tears threatened to cone through, but I wouldn't let them out.

"True," he turned away. "But how dare your filthy blood-traitor boyfriend, even TOUCH my girlfriend?"

"Excuse me? How dare your slutty little girlfriend kiss MY boyfriend?" I retorted.

"Pansy's a bitch but she's better than that weasel you call a boyfriend." he growled.

"Are you saying your pug-faced slut is better?"

"Well of course!"

I sighed. "Alright, look. I didn't call you here to argue about this. After what happened, to me, they're both dead. So that's why I called you. I wanted to see if we could work out a little plan of revenge." I said.

"Do you have a plan?" he asked.

"Of course. I'm the brightest which of our time, remember? And I want them to suffer." I said.

"Sheesh. They way you're acting right now, I would've believed you if you said you were a Slytherin." he said.

"That's not the point." I said. "So I do have a plan. Well, somewhat of a plan. The only downside is that...uh...we have to date."

He suddenly smirked. "Geez, Granger, if you wanted to date me so bad, you didn't have to make up this stupid story. You could've just asked."

I shoved him against a bookcase and grabbed his tie tightly so I was slightly choking him. "I'm anything but making up a stupid story." I snarled. I let go, and he looked at me.

"You're definitely a Slytherin at heart." he said.

I rolled my eyes. "So do you want to get back at Ronald and Pansy?" I asked.

"Well of course. What happened come damage my image."

I rolled my eyes again and stuck my hand out. "So do you agree to go out with me just so we can get revenge on them? And that this is only for that purpose?" I asked.

"You really aren't kidding about the whole thing?" he asked. I shook my head. He sighed. "Very well.", and he shook my hand.

And that, was the day that all the chaos started.
