A/N: A supernatural MariChat for you for Halloween :)

If something or someone isn't mentioned, there's a reason why ;)

Chapter 1

There it was, once again.

Marinette picked up the thornless rose from the bookshelf in the wall behind her bed. As usual, she pressed her nose into the bloom and took a deep sniff, inhaling the rich scent.

Every morning for the past month she had been waking up to a single, blood red rose on the same shelf. At first she thought it was a present from her parents, and thanked them for it. However, they denied having anything to do with it.

Maybe you bought it and just forgot about it, they had suggested.

Her parents were terrible at keeping secrets. Whenever they tried to, their lips would start to twitch in their efforts to not break down in giggles. But when she had asked about the rose, their faces were perfectly confused. They truly didn't do it.

Then who did? The only ones who lived there were Marinette and her parents.

That meant some stranger was coming in and leaving them there. They literally had to climb over her to put it on the shelf, somehow without waking her. She considered herself to be a light sleeper, so this stranger must have been quick and light on their feet.

At first she had been utterly terrified at the thought of some mystery person intruding in her room. She tried staying up one night to catch them, but sleep ultimately ended up pulling her into the abyss of dreams.

There was a rose the next morning.

She had even told Alya about this, but the girl only giggled and teased her, claiming she had a secret admirer. Marinette had dismissed the notion with a laugh before going on about how stealthy they were, how they managed to leave roses there without even slightly rousing her.

Her best friend pointed out that Nathanael was really quiet, perhaps he was leaving them there, since they both knew the artist had a crush on her. Marinette highly doubted it, she didn't think the boy was the type to do something like that. And now that she had a possible face to the suspect? The situation seemed more creepy than romantic.

The blackette then inclined her head over her shoulder to steal a look at the red-head. His face was looking down to his sketchbook as he drew, oblivious of the two girls discussing him.

He was a nice guy, but she just didn't feel that way for him. She honestly dreaded the day for when he gathered up the courage to ask her out. She didn't want to have to hurt his feelings.

...

"There was another one this morning," Marinette informed Alya quietly as she took her seat for class.

"Pretty soon there'll be no more roses in Paris," Alya joked. "How long has it been now?"

"A little more than a month," Marinette replied, glancing away.

"Girl, you need to find out who this admirer is already. This introduction is way overdue," her best friend advised.

"I tried!" She protested. "But I always end up falling asleep before I can see them."

"Leave a note asking them if you can meet. I'm dying to know who they are!"

Marinette grinned and raised an eyebrow. "Shouldn't I be the one saying that?"

Alya snickered and returned a sly grin. "Hey, it's not my fault my inner journalist is bloodthirsty for more details."

The girls laughed until Mme. Bustier came in and started that day's lesson.

...

Marinette stared down at the paper on her desk in her room. She was about to go to sleep for the night and was seriously contemplating taking Alya's advice and writing a note to the stranger.

But what would she say? She wasn't very good with words.

She sighed and tapped her pencil against the paper. This is why she preferred designing clothes, there were hardly any words involved.

She thought back to her main objective: finding out who the person was. Maybe she should just ask them outright who they were, it was straight to the point and not easily misunderstood.

With that mindset, she bent her head down closer to the paper and began to write.

Dear Stranger,

Thank you for the roses, they are very beautiful. But I would like to know who you are, and why you're leaving them. After a month of this, isn't it time we meet?

From, Marinette

The blackette smiled and picked up the paper, holding it out for inspection. It was short, but to the point without being rude. Perfect.

She turned off her lights and used the staircase to get into bed. Before she went under the covers, she placed the note on the shelf exactly where the person was leaving the roses, that way they wouldn't miss it.

...

Marinette had to admit she was disappointed when she woke the next morning. She wasn't disturbed from her sleep at all during the night like she hoped she would've been. She thought that maybe they would've read her note and revealed themselves to her.

Rubbing the sleep from her eyes, she turned to the shelf, expecting a rose.

Her eyes popped open, fully awake.

There was indeed a blood red rose waiting for her, but also a folded piece of paper below it. Marinette didn't fold her note, so this had to be a new one!

She opted to skip smelling it in favor of reading the stranger's letter first.

Dear Princesse,

Marinette paused and raised an eyebrow. Princess?

I'm very happy you like them. I picked the best at my disposal for you so I'm very glad you're not disappointed. As for who I am? My, you're an inquisitive little princess, aren't you? Though, I commend you for holding back your curiosity on my identity for this long. I'll indulge you for your patience. You may know me as Chat Noir. While I would love to officially meet you as well, unfortunately it is going to have to wait. I cannot tell you why just yet, I implore you to be patient.

The reason why I'm leaving the roses? Well, I would think as to why a gentleman would leave a lady flowers to be quite obvious, wouldn't you agree?

Forever and eternally yours,

Chat Noir

The letter was written in the most elegant script she had ever seen. It went far beyond than what she had learned in elementary school cursive lessons. Every loop and swirl of the words were smooth and perfect with no flaws that she could spot.

Chat Noir, huh? What kind of a name was that, anyway? Still, at least she had a name to place on the stranger, and knew it was a male. And apparently, he was interested in her, given her intuition was right about the last two lines in the letter.

Forever and eternally yours,

She deduced he felt rather strongly for her despite never having met before. How could he say something like that without knowing her?

Despite her reasoning, blood rushed to her cheeks and her heart beat was just a tad quicker. It felt...exhilerating to have a man trying to woo her. If this was happening in a story she was reading, she'd probably be swooning and going on about how romantic it was.

The blackette picked up her phone to text Alya to come over. Hopefully she could make sense of this and try to sort out her conflicted feelings.

...

A wolf's howl pierced the night air, the sound going straight to the blond's ears.

Years ago he would've winced at the loud volume, but he had grown so used to it by now that it didn't bother him at all. Instead, he grinned and ran to where the sound originated, expertly dodging trees and bushes in his wake.

Due to his impressive speed, he was upon the werewolf in seconds. The creature's lips turned up into a smile before his body began to morph.

"Hey, Nino."

The boy got off his hands and feet and rose to a stance. "Hey, dude! Let me guess, just get back from that human's place?"

The blond's emerald eyes narrowed. 'That human'?

"Her name is Marinette," he hissed, fangs on full display.

Nino frowned and took a step back while holding his hands up in a sign of surrender. "Okay, okay. No need to go all vampire on me."

Chat Noir sighed, the tension leaving his body as his shoulders slumped over. "I'm sorry. It's just-"

"A vampire is protective of their Loved One. I know." Nino offered a small smile, showing he understood him and meant no malice.

Chat's lips curled up. "Thanks."

"But, if I can suggest something..."

"Go ahead."

"Talk to her already!" Nino exclaimed, the sudden rise in his voice making his best friend flinch. "It's been over a month, now, you have to move things along. She's going to get bored if you don't do something."

The vampire smirked and shook his head. "That's where you're wrong, Nino. She left me a note tonight, asking about me."

"She did?!" The man asked, hazel eyes opening wide. "What did she say?"

"You know, you remind me of Lady Chloe sometimes since you always want to know what's happening," Chat chuckled.

The werewolf glowered. "Don't compare me to her, dude. I just want to know about your love life, as all best buds do. Or, more like, 'lack of love life' since you refuse to go anywhere with this girl."

Chat Noir sighed, his smirk vanishing. "I can't. She'd be terrified of me."

"We don't know that. But we can get back to that later. Tell me what she wrote!"

"She basically just asked who I am and why I'm leaving the roses. She may have also wanted to meet..."

"Dude?!" Nino yelled angrily. "She wants to meet you and you didn't go through with it! What are you waiting for? Oh my God, do I have to tell you everything?"

He rolled his eyes at his friend's melodramatics.

Nino managed to settle down enough to ask his next question. "Did you reply to her?"

Chat nodded. "I did. I basically told her that my name is Chat Noir and kind of answered why I was leaving her the roses."

Nino raised an eyebrow in curiosity. "I hope you wrote more than what you told me just now. You tried to flirt at least, right?"

If Chat was human, he was certain his cheeks would've been full-blown red. "I-I think so," he stuttered, rubbing a clawed hand along the back of his neck. "I tried to. I hope it worked."

Now it was Nino's turn to smirk. "Judging by your face, I'd say you did. I know you can't be as innocent as you let on to be sometimes."

The blond let out an airy chuckle. "I suppose not."

"But seriously." His friend's expression turned neutral. "When are you going to meet her? This can't go on forever."

"I know," Chat answered. He looked away from Nino's penetrating gaze. "But like I said before, she'd be terrified of me."

"And like I said before, we don't know that. As your best friend, I can say that you're an awesome guy. She'll love you if you give it a chance."

"That won't matter. She'll only see me as a monster," Chat insisted.

Nino crossed his arms. "If you think that, then why bother with her at all?"

The blond stayed quiet at that. Deep down he really wanted to speak properly to Marinette, learn everything about her, cherish her and give her his undying love for the rest of eternity. But his insecurity kept getting in the way of that dream.

He remembered when he first saw her. He had been travelling in the night, jumping from building to building, when the sweetest smell he had ever came across drifted to his nose. It smelled like vanilla and sugar, and the scent made his fangs ache in need of it.

He tried to find out where it was coming from, only to find a lone girl walking down the street below him. She had a backpack attached to her back and was walking rather quickly. Understandable, humans could get hurt if they were out at late hours.

The vampire got as close as he could without alerting the girl of his presence. He was able to get in front of her and see her perfectly from his perch on the roof of a flower shop.

He had to admit, he was stunned by her beauty. It made him wonder how a human could look like that, vampires were the only sorts of beings who possessed ethereal allure. Yet here was a human girl, entrancing him without even knowing it.

She had midnight-colored hair that was pulled back into two twin-tails, along with fair skin with freckles running across her button nose. Her eyes reminded him of the ocean, they were such a brilliant blue.

Intrigued, he watched her go all the way to a closed bakery. As she slipped in through a side door, he in turn retreated to a balcony on the roof of the bakery. Standing still, he used his superior hearing.

"Maman, Papa, I'm back from Alya's!"

He smiled. He already liked hearing her voice and wanted to hear more.

A man started to talk, most likely her father. "Marinette, you can't keep staying out this late. It's dangerous to be out there all alone."

Marinette. It was a lovely name.

"I know. I'm sorry."

"It's okay, sweetie," a woman's voice said. That had to be Marinette's mother. "Just try not to leave so late anymore. Go to bed, you got school in the morning, you know," she giggled.

"Right. Good night!"

It seemed she loved her parents very much, and was a kind, sweet girl. He was glad she had beauty on the inside as well as the outside.

The vanilla and sugary scent was stronger when she came into her room, right below the balcony. It took all of his willpower to not jump in the room, tug her hair back leaving her neck bare to him, and sink his fangs in.

He shook his head to clear it. He couldn't do that to her, not to this girl he had taken an interest in.

When her light shut off, he peeked down into the skylight to see her laid in bed, rolled over to one side with her eyes closed. She looked so peaceful and beautiful, it was hard to take his eyes off her.

A wild idea came to mind. Suppose he could woo her, have her fall for him. She'd be his Loved One. He could ravish her with love and affection, make her feel like the only girl that mattered in the world, spoil her with gifts and-

The vampire blinked and grinned.

He had to find a rose.

Chat released a breath through his nose. Vampires may not need to breathe, yet he chose to do so anyway. It was probably since Nino had to and growing up with him made some of the werewolf's traits rub off on him.

"Nino. I just...what if she really doesn't like me? I mean, vampires suck blood from people in order to live. Any human would be afraid of us."

The man rested a hand on his best friend's shoulder. "And that's why you need to prove to her that you won't do that to her. Make her not be afraid of you. Besides, you know your pops is getting impatient."

He was right, there. His father had been pushing him to get married for months, now. He had first tried to set up a match between his son and Lady Chloe. But Adrien was vehement in his refusal of the union. Chloe was a childhood friend, but not a wife and even much less so of a Loved One.

Adrien had gone up to his father about a week after he began leaving roses for Marinette. At first he was angry that he chose a human of all creatures to romance, but seeing his son's devotion to her, made him ease off.

Now, he was pushing Adrien to just get together with the girl, turn her, and produce an heir.

Why couldn't anybody understand that it was a lot more complicated than it looked? Vampire and human matches were rare. Most of the time when a vampire fell for a human, the human was horrified and wanted nothing to do with them.

He'd truly be dead if that happened with Marinette.

"Trust me," Nino urged, staring straight into his friend's glowing eyes. "Talk to her. This meeting has been long overdue and you need to make your move. What if some other guy gets to her before you?"

The thought of another male trying to romance his Loved One made a possessive growl rip out of the blond's throat and his fangs to extend.

Nino grinned. "There we go."

A/N: So, what did you think? I hope you liked it :)

A Loved One is a term a vampire uses for their 'mate'. Most of the time it could be their wife, but sometimes a vampire will bestow it on someone if they fall deeply for them before they are married, like Adrien with Marinette :) The term was invented by yours truly ;)

Also, yes, vampires can reproduce in this story. Let's ignore the fact this wouldn't normally be possible since they're dead, kay?

And, the Miraculous exist, although they have an entirely different purpose for this story. You'll learn more later :)
