Marc x Nathaniel Yandere Oneshots

You're shaking so much, love...

Lila Diablo Rossi has been reported dead. The Akuma class, sans a few, mourned the loss of their fellow student.

According to the police, she committed suicide by jumping off the roof of the mayor's hotel, and even left a suicide note that revealed all the lies she told

And investigation started at school. The Akuma class immediately pinned the blame on Marinette and say she was the cause for her suicide, but when the officers showed them the note, they shut up, and started to feel so stupid

The only person who didn't seem at all affected by Lila's suicide was Nathaniel, who kept a neutral look on his face the entire time his class was being questioned

"It's sad what happened." Marc said as he and Nathaniel ate their lunch "I-I mean, sure, she was terrible, but nobody should commit suicide."

"Yeah, it's a shame." Nathaniel replies, then takes a bite of his apple "And she died right on the day of the class picnic."

"Excuse me?" Marc asks, confused "You guys didn't hear about her death until today."

"What do you mean?"

"Well, how do you know she died on the day of the class picnic? She could've died the day before, or-" Nathaniel cuts him off

"Oh, the officers confirmed it, actually." He says quickly

"Oh. Okay." Marc replies, satisfied with the answer

Throughout the rest of the day, Marc couldn't shake the feeling that something was wrong. He trusted Nathaniel, but the way he's reacting to Lila's death is so odd.

Sure, the redhead didn't like her because of the constant lying, and she always ripped up their work, claiming it was because of some fictional disease, but he just seemed so unfazed by something so serious

"Hey, Marc!"

The writer is snapped out of his thoughts when he hears Marinette call out his name

"Oh, hey Marinette." He managed to say without stuttering "What's up?"

"I heard you talking to Nathaniel at lunch..." She replies, looking kind of worried "The police officers never confirmed the day Lila... You know."

Marc is taken aback. Why would Nathaniel even lie about something like that? And how did he know?

"Th-then how-"

"I don't know, but no one else knows the day that happened." She looks and sees Nathaniel, sitting on the steps, sketching in his sketchbook "Look, just keep an eye on him." She walks away, leaving Marc with his thoughts until the bell rang

The next day, the police have revealed new evidence to the school regarding Lila's death. The hotel had cameras on the roof, and one of them had a clear view of what happened

It was blurry, but people could clearly see a figure dressed in all black sneaking up behind Lila, pushing her off the edge of the roof of the hotel, placing the suicide note on the ground, then walking away

But one thing really caught Marc's eye- The timestamp in the corner. It was the date of the class picnic...

And no one else noticed it, but Marc could clearly see the purple bracelet around the suspect's wrist... It looked just like the one he gave Nathaniel...

"Rainbow," Marc flinched at the nickname "why are you shaking so much?"

Marc hadn't even realized he was shaking. He didn't even realize that the school day had ended and that he and Nathaniel were walking home together

"I-I'm fine..." He says "But, I wanna ask you something, and I want you to be honest with me."

"Of course..."

"... Marinette told me that the police officers didn't tell your class when Lila died. So how did you know the date of her death?" He questions

"Rainbow, you shouldn't be so concerned over this." He said while holding his hand "Just be glad that she's gone. Everyone trusts Marinette again, Adrien won't have to worry about her clinging to him, and our hard work won't get destroyed anymore."

That just sent chills down his back "B-but-" He's silenced when Nathaniel kisses him

A week had gone by. Marc hasn't brought up Lila's murder around Nathaniel, but he still couldn't shake the feeling that his boyfriend might have played a part in her death.

"Rainbow, I'm sure whoever did it thought it was for the best."

Marc could hear the annoyed tone of voice, but continued to pry

"How could you say that? Sure, Lila was horrible, but-"

"Rainbow!..." He snapped, then calms down when he sees the scared look on Marc's face  "...I told you, don't worry about it. Who cares if it was suicide or murder? She's gone now." He wraps his arms around Marc's waist, and can feel him shaking "Sweetheart, you've shaking so much lately. Why don't you lie down for a bit?"

The truth finally came out. Marc was staying at Nathaniel's house while his parents were out of town. He was looking for his phone, and went to look under the bed. But what he grabbed wasn't his phone- He grabbed photos of people taken without them knowing. A lot of them had a big red 'X' drawn in marker.

And on the backs of every photo there was a list of what looked like misdeeds

Flirted with him too much.

Called him the f-word.

Kissed him without consent.

Marc started to recognize the people in the photos. They each did one of those things to him. A few of them were even students that went missing a few months ago. He looked through every photo in the pile until he found one of Lila with a massive red 'X'.

He flipped the photo over and found a long list of her misdeeds

Torments Marinette.

Harasses Adrien.

Lied to the class.

Made Marinette an outcast.

Calls Marc The f-slur when he isn't around.

Ripped up Marc's script.

Tripped Marc in the hallway.

Stole Marc's work, claimed it was hers.

Works for Hawkmoth.

And many more...

He did it. Nathaniel actually did it. He killed Lila, and so many more people. And he's probably going to kill more people.

"Rainbow?" Marc froze when he heard the nickname he used to love "What are you doing?" There was a bit of insanity in his voice

"You... You killed her... A-and the others... How could you?"

"Rainbow, they were hurting you. They tried to take you away from me. They wanted to tear us apart. I did this for you and only you, Rainbow."

He slowly approaches Marc, takes the photos, and notices the boy once again shaking in fear "Oh, baby. You're shaking again. It's because you want me, right? You're not scared, are you?"
