Poisson d'avril

Here, have a half-baked April Fool’s Day fic my brain decided to wake me up for. For context, one of the most popular jokes for April 1st in France is taping paper fish to each other’s backs, the more original the fish the better (my childhood is filled with trying to sneak behind teachers' backs to tape one on them; they were very chill about it, tbh). Poisson d’Avril is also what you say at the end of a joke on that day (think "sike", but festive). More about this great tradition that apparently dates back to at least 1466 here.

Hope you enjoy!

Marinette loved April Fool’s Day at Françoise Dupont. The school was always buzzing with little pranks at that time of the year, the blooming spring giving a wonderfully cheerful backdrop to the shenanigans the collégiens were up to.

These were all very light-hearted, if sometimes a little elaborate.

As usual, some students had been found early in the morning in the classrooms, thwarting their attempt to recreate the legendary horizontal fiasco of 20XX, where everything had been set up to look like the rooms had been flipped by 90°. Mr Damoclès had let them go mercifully, thankful that the students hadn’t been tempted to glue everything to the ceiling in an effort to one-up their predecessors. Somehow, he wouldn’t have put it past Kim and Alix to try and coordinate the project, as a last hurrah before heading on to lycée.

There were also seemingly well-meaning classmates offering chouquettes or donuts in the courtyard, which Marinette knew to stay well away from, knowing the former were likely sprinkled with coarse salt, and the latter filled with the likes of mayonnaise instead of jam. She’d been in their shoes a couple of years prior, building her classmates’ trust by bringing them the sweet delicacies every day for a week, and switching on April 1st as a joke.

Heading to class, she heard a lot of laughter, people telling jokes, or trying to see how far they could take a story without it being called out on it (this year, Nino had Kim panicking over a brevet exam part they supposedly had, which was a step down from the previous year, where he’d convinced him that everybody needed to come in dressed up in medieval costumes, and that he’d landed the court jester role; his friend had turned up the next day in a full outfit, complete with bells on his hat and shoes, and upon discovering the deception, had decided to make good use of them and make the joke everybody’s problem).

However much she enjoyed those kinds of pranks, though, Marinette’s favourite remained the classic poisson d’avril: taping paper fish to people’s backs. It was something anyone could take part in, as a predator or a prey, with or without premeditation. You didn’t necessarily need scissors and tape, if you managed to steal some from somebody else’s back.

Marinette liked to take it seriously. Done right, the exercise demanded stealth she’d had even as a little kid, and had honed ever since being chosen to become Ladybug, as well as creativity she had piles of. She’d stayed up the previous night, making plenty of fish varying in size and colour, some tailored to her friends, like the Rena Rouge and Carapace ones that were intended for Alya and Nino respectively. She’d of course also made the rest of the Miraculous team, as well as some other designs based on Kitty section, her classmates, or celebrities.

As always at the end of the day, Rose walked around with a whole school on her back. It wasn’t clear if she was completely oblivious to it, or if she knew what was going on but enjoyed the giddy giggles of the people who managed to add an extra fish in, or take one off.

The only person who’d managed to escape the prank so far was Adrien, and it wasn’t for lack of trying. Kim, Alix and Nino had gone to great lengths to get at least one fish on his back, even recruiting Markov to sneak behind him, but the boy seemed to have a sixth sense.

No sooner did he hear the faintest of ruffles, that his head would jerk up, eyes darting around to figure out where the sound had come from, thwarting any efforts, no matter how elaborate they’d been.

Marinette had been reluctant to target Adrien, despite having a special fish for him, complete with his stripes and an orange-tipped tail, but as the day went by and more people joined the challenge to trick him, she felt the urge to compete rise in her chest and started unwillingly tracking his every movement, trying to find a breach in his focus.

It was a fastidious process, even for someone who enjoyed watching Adrien happily live his life, but it paid off around the end of the day, just after the last bell.

Marinette noticed that Adrien’s shirt looked a little rumpled around the back as they were retrieving books from their lockers, and approached him calmly.

“Adrien?” She announced her presence when she was right behind him, surprised that he hadn’t turned around yet. He almost jumped out of his skin at the sound of her voice.

“Marinette!” He yelped, a hand flying to his heart. “Sorry, I didn’t hear you approach.” He chuckled nervously.

“No, I’m sorry I scared you!” Marinette looked down, apparently sheepish. In truth, she was cursing inwardly at the missed easy opportunity. Adrien had been at ease with her coming closer, which she assumed was because it was the end of the day and he’d started letting his guard down; she could have gone about her business and he would’ve been none the wiser. She shook her head; it didn’t matter, she’d just go on with her original plan. “It’s just that… well, it’s stupid, but the back of your shirt is a little creased, and I know how important your appearance is to your family so… Do you mind if I fix it?”

“Thanks Marinette, that’d be awesome.” He smiled at her in a way that would have made her lose her cool, had it been any other day. But she was on a mission, and there was no way she was letting the opportunity of pranking Adrien when nobody else had managed the feat go by.

“Okay, let me just…” Marinette reached into her purse and took the first piece of paper she felt, before gently taping it to Adrien���s shirt, making sure to smooth the fabric at the same time so he wouldn’t realise what she was doing.

“There, all done!” She smiled when she was satisfied the tape had adhered well enough.

He smiled back at her, but was interrupted in his thanks by Nino and Alya calling for them to hurry up.

“Today was really fun, I’m so glad I got to experience it first hand,” Adrien beamed as the group walked out of the building, Nino and Adrien a little ahead of the girls. “And I’m really proud that I survived it without getting pranked!”

Marinette bit back a laugh, eyes darting to his back.

“I wouldn’t be so confident, Sunshine,” Alya replied, untaping the fish from his back and handing it to him.

“What…” Adrien stopped in his tracks, looking at it, and particularly Marinette’s signature on the back of the piece of paper, in disbelief. He turned around with a look of mock betrayal. “I can’t believe you’d do this to me!” He pouted.

“I couldn’t just let you off the hook,” she shrugged with a small smile, making a mental note to reuse the phrase with Chat Noir when she saw him later. He’d enjoy the pun.

Adrien let out a small chuckle as he turned the fish around, but the sound died as he saw the pattern. The colour drained from his face and he froze as he took in the black and green colour scheme and the fish’s whiskers.

“Adrien? Is everything okay?” Marinette frowned, noticing his change in body language.

“Yeah, um… Can I talk to you for a second?” He looked up at her.

“What a great idea!” Alya pushed Marinette towards Adrien before hooking her arm through Nino’s and starting to go down the stairs. “We’ll see you guys tomorrow!”

Marinette thought she heard her add “Can you believe they might get together over an April Fool’s joke?”, as she waved them off absentmindedly, but her gaze met Adrien’s troubled one and she decided she’d deal with her best friend later.

“What’s up?” She asked, feeling a blush creep up her cheeks; the adrenaline from succeeding her challenge was evidently starting to wear off.

“What’s this?” Adrien asked cautiously, handing her the fish.

Marinette took it cautiously, saw the pattern, and smiled. “It’s a poisson-chat noir,” she said proudly. It was a bit of a shame she’d picked that one for Adrien, but she guessed she couldn’t have kept it for her partner anyway, given that she’d signed it. Still, she thought he would have liked the joke. Especially if it came from Ladybug.

“How did you know?” he murmured, looking at her incredulously. She tilted her head, raising her eyebrows at his cryptidness. He explicited his thoughts. “I saw the fish you gave Alya and Nino, and the one you managed to pin on Chloé; they were all references to their superhero selves. And now you get this one right as well… How did you know?”

It was Marinette’s turn to freeze and feel the colour draining from her cheeks. “I… I didn’t. I picked one randomly when I saw an opening.”

“Oh.” She saw the cogs turning in Adrien’s brain while she felt her own shut down, still processing one important piece of information.

“Adrien… Are you Chat Noir?”

“Um… Poisson d’avril?” He ventured.

“Adrien.” She repeated sternly.

“Okay, fine, you got me.” Adrien huffed, raking a hand through his hair. “Please, don’t tell Ladybug.” He pleaded.

“Too late, I’m afraid.” She dug out her poisson-Ladybug and taped it to herself. She saw Adrien’s eyes grow as wide as his smile before being engulfed in a hug and feeling his lips on her forehead. “Kwami, we really might get together over an April Fool’s joke,” she muttered against his chest. If the heat she felt at the tip of her ears said anything, she probably was as red as Ladybug’s costume, and it probably wouldn’t go unnoticed.

“What was that?” Adrien pulled out a little from their hug to look at her.

“Nothing.” She smiled, and took his hand. “Now come on Chaton, we have some things to discuss, and we should probably go somewhere more private.”

“You know I’d follow you anywhere, my Lady.” He picked their entwined hands and kissed hers.

Really, she thought as they made their way towards her parents’ boulangerie, she loved poissons d’avril.
