A/n: hmnnn I'm gay for Grell FFUUCK- please ma'am just a pinch of tiddy.

You were livid, absolutely fuming.

Turns out, you'd been cheated on. For years. After the sadness and betrayal simmered, rage took its place.

You were going to kill him.

And you had a good idea of how to do it without being caught too. So what if you'll end up in hell for this, that fucker deserved to die. He would be at a ball tonight, with his side girl. The girl didn't do anything wrong, she was just as oblivious as you were so you were keeping her out of it. It was him you wanted dead. Thanks to the masquerade dress code you could show up under a mask and conceal your identity, only revealing it when you had him cornered and begging for his life.

So you showed up at that ball, knife under your dress. That fucker was going to die for what he did.

Under the cover of an elegant black mask of lace and feathers, donning a matching black dress and heels you waltzed in as if you were meant to be there. Looking around and quickly spotting the cheating fucker talking to his side girl your eyes narrowed in anger and you sighed in frustration. Of course he had the nerve to wear the suit YOU gave him. Butlers were walking around with food and drinks, and maids stood by if anyone needed help. You'd have to avoid being noticed by them, although with the amount of people here it wouldn't be hard.

Among all the boring colours of black suits and white gowns, there was one thing that stood out. A girl, head to toe in red standing off the the side with a glass of wine in hand. She seemed to be watching the crowd, maybe waiting for someone. But her long hair that hung over her shoulders and her matching red mask made her stick out among the others.

She was bold for wearing red to a black tie. Admirable.

But that wasn't what you were here for, you were here on a mission. A butler passed you, offering glasses of champagne and you took one just to chug it down for a boost of confidence.

You watched from the sidelines, waited, anger brewing inside you thinking of how long that man lied to you, screwed you over. You put everything into that relationship, and he had the nerve to throw it all away as if it were nothing. How could he? No...

HOW DARE HE.

Finally around the stroke of midnight, he left the ballroom slightly drunk heading toward the bathroom. You knew now was the chance, following him and slipping through the crowd un-spotted you stalked behind him far enough so he couldn't hear your heels clicking on the ground. Down the winding halls of the mansion the sound of the ball got further and further away. No one would hear him scream this way.

He turned into the bathroom, and closed the door. You stood outside and waited, hand gripping the knife under your dress. As soon as he opened that door you'd push him back in and attack. You felt a little bad for the owner of the mansion for having to clean up a dead body, but your anger for this sack of shit overtook that feeling.

It didn't take long for you to see the door handle turn, and the door to crack open again and all that anger and adrenaline came bursting out. You launched at him, shoving him backward into the ground and pinned him down to the floor. He bashed his head on impact and yelped in pain.

"What the fu-"

"YOU THOUGHT YOU COULD GET AWAY WITH CHEATING HUH?" You screamed.

"(Y-Y/N)?! What are you-" he stammered.

"You thought you could cheat on me for YEARS and get away with it? REALLY? I put EVERYTHING into this relationship, EVERYTHING! And you just threw it all away for some other girl. Was her pussy really that worth it? REALLY? And she has no idea that you're a cheating whore too huh? BASTARD! UNFAITHFUL MOTHER FUCKER!"

His eyes widened, realising he was caught and you were absolutely not fucking around.

"SHE DID'NT MEAN ANYTHING- (Y/N) WE CAN TALK ABOUT THIS-" he cried.

"Really? TALK ABOUT THE SEVERAL YEARS YOU SPENT FUCKING ANOTHER GIRL? If you'd just broken up with me when you decided you wanted to fuck her this wouldn't have happened, the fact you LIED TO ME, CHEATED ON ME AND LEAD ME ON FOR YEARS IS YOUR OWN FAULT" you screeched.

He tried to wriggle out of your grip, but his half drunk state made him too weak to do so under your body weight and anger.

"(Y/N) STOP BEING A CRAZY BITCH AND-" he yelled.

"FUCK YOU. I WILL BE A CRAZY BITCH BECAUSE YOU CAUSED THIS. You dug your own grave you cheating slut, now LIE IN IT" you seethed.

Before he could even respond, you brandished the knife and used all your force to drive it into his heart. He screamed, thrashed in pain and blood began to seep through his clothes. You pulled the knife out and stabbed him again.

In and out and on and out and in and out, that knife chopped up his chest more times than he could cheat on you. Eventually, he fell limp, his eyes rolled back and his breathing stopped. Blood covered the floor, your dress and his clothes. You took a second to catch your breath, and looked down at that lifeless body under you.

No remorse. If it was anyone else you'd feel absolutely awful. But not him, not after what he did.

"Mother fucker..." you muttered.

Suddenly you heard heels clicking across the floor behind you and your blood ran cold.

"Bravo! What a show, well done! I've never seen a revenge killing so passionate and violent before! Thrilling, truly"

You turned to face the person who'd caught you, and to your surprise it was the girl in red you'd seen before. You took a second to process what she said, she was praising you? For killing someone?

"You're... not horrified?" You replied.

"Horrified? Darling that was the best murder I've ever seen! Truly spectacular. And besides, no cheater dwarves life. Love is the most important thing in life and in death and anyone that chooses to throw that away deserves all that's coming to them" she replied.

She walked over to the body, kicked it slightly to make sure he was dead. Although it was definitely clear from all the stab wounds he was dead.

"What a pathetic man. A sad excuse of a human" she muttered.

She took a pair of scissors from down her dress and cut slightly into the body, and to your shock what looked like film reels shot out of it. Film reels that showed his whole life. Including all the times he cheated on you. The red girl watched them, scoffing at the cheating and when the reels ended she took a book from her thigh garter.

"I wish I could have bought my chainsaw to hack up this man but it was too big to hide in this dress. Stupid scissor scythe... anyway run of the mill cheater gets what's coming to them, nothing to note" she said.

The book went back into her garter and after washing the blood from her scissors they went back down her dress. She looked down at the body again, pressing her heel to the man's face.

"Ugh what a dick- alright are you going to get away with this murder or not?" She said.

You were thoroughly confused about what just happened and what she just did, but she seemed to be on your side here.

"Depends, will you dob me in?" You asked.

"Nope, not my job. Plus he deserved it" she replied, holding out a hand to help you up.

You took it, and her soft hands strongly pulled you to your feet.

"I need to burn this dress" you said.

"There's a fireplace in one of the bedrooms here, been to this place before" she replied.

She held onto your hand and lead you down the halls to one of the bedrooms that had a fireplace going to keep the cold mansion cool.

"Perfect, although I didn't think this through... I only have my corset and slip underneath this" you said, pulling off the blood soaked dress not really caring about stripping in front of this strange girl.

She was already helping you cover up a murder anyway.

You tossed the dress in the fire and watched it burn, also throwing the knife in and watching the wooden handle burn away and the metal
blade get singed. You thought about stealing a dress from one of the closets, but felt something over your shoulders and when you turned you found the red girl covering you with her red jacket.

"Impressive no blood soaked through the dress into your corset. But still don't be walking around at night like that, men are disgusting" she said, buttoning you up.

You took a second to process what she was doing, and the warmth of the coat she'd been wearing kept you somewhat grounded in this weird situation.

"Why are you helping me?" You asked.

"Men are trash. Especially cheaters, I get why you did it. Plus, it may not be my job to report a murder but it's my job to make sure they run smoothly. Also I can't have a fellow lady harassed in the streets for her lack of a dress" she replied.

You were a little shocked at her kindness and lack of fear or horror with you. But, you weren't going to complain, you didn't need her changing her mind and dobbing you in.

"You sure I can take your coat?" You asked.

"I have plenty of red coats. My main one is at home anyway, I can afford to loose a night one" she replied.

Suddenly you both heard screaming down the hall, and you knew immediately that someone found the body.

"Shit" you whisper yelled.

"This way" the red girl replied.

Taking your hand she pulled you out the room and skidded down the halls to the back entrance where no one was around. Making your escape you both ran through the small wooded area and back onto the streets away from the mansion.

"Thanks" you panted.

"You're welcome. Damnit that went overtime I have another soul to get, it was nice meeting you (y/n), he absolutely deserved to die" she replied, quickly checking she had everything and turning on her feet to run off.

In the strange events of the night your mind raced with confusion but there was one thing that you happened to realise right before she left.

"WAIT!" You called out.

She stopped, turning to face you.

"I never got your name"

She gave you a smile, and it was then you realised her teeth were rather sharp and pointed.

"Sutcliff. Grell Sutcliff" she replied.

"Grell... interesting name... thank you" you replied.

"We'll meet again some day, I know it"

And with that, she was off to do whatever it was she was off to do. You stood there for a moment just letting everything that happened sink in, before you turned to walk home. You could smell a sweet aroma on the collar of the red coat you were given, a floral one. Rose? Maybe pansies? Windflower? Whatever it is it was nice.

Grell smelled nice.

She was a strange person, but definitely someone you'd never forget. I mean, a stranger helping you cover up a murder doesn't happen every day. And what was up with the film reels? Absolutely an unforgettable night. You hoped you did meet again one day, and you hoped that fucker suffered in his final moments.

Hang on... how did she know your name?
