Lady Noir and Mister Bug looked out over the city, gazing at the people walking, chatting, and working around the Louvre.

"You ready?" Lady Noir asked, frowning down at the familiar landmark.

"As I'll ever be." Mister Bug hummed, straightening his back and stepping to the edge of the roof. "Let's do this."

Nobody noticed the two figures standing at the edge of the building, which was lucky; the couple was still preparing themselves.

Mister Bug fiddled with his necklace that held the two magical earrings, and looked at his girlfriend, her black hair pulled back into a long braid, her excited, but nervous, smile lighting up her whole face.

Mister Bug took one last deep breath, then called out to the people below. "People of Paris, may I have your attention?"

The citizens looked up, gaping at him in shock, no doubt wondering where their normal heroes, Ladybug and Chat Noir, were.

Mister Bug waited until a citizen had whipped out their phone to continue.

"My name is Mister Bug, and this is Lady Noir. For the next few months, we'll be replacing Ladybug and Chat Noir as they attend to some personal matters. Despite not having as much experience as they do, we're here to aid you as well as we're able." Mister Bug lifted his hand in a single wave, grinning at the crowd. "As long as we're here, your safety is ensured."

The crowd didn't cheer. Instead they stood stunned, as if unsure what was going on.

By the time even one of them recovered, Lady Noir and Mister Bug had already backflipped off the roof into a back alley.

The moment they touched down, with a silent command, their disguises fell away.

Mister Bug's mask revealed a young boy with yellow hair and bright green eyes.

Behind Lady Noir's mask was a blue-eyed, dark-blue-haired, pale-skinned, smiling girl.

"How'd I do, Marinette?" The boy asked, dusting back his golden locks.

"You did amazing!" Marinette tugging on the ponytails that had miraculously replaced her braid. "Couldn't have done it better myself!"

"That means a lot coming from Ladybug." The boy chuckled, grabbing her hand tightly.

"Aw, thanks, Chaton." She giggled, squeezing back. "You're not so bad yourself."

The boy hummed an immodest noise of agreement.

The two began to leave the ally, phasing into the busy streets of Paris, France.

"When are you leaving for your…'round the world trip?" The boy asked, sighing deeply as he led her deeper into the crowd.

"Um…" Marinette thought for a moment. "Nine days."

"So soon…"

"Well, it's why we did this whole Miraculous switch. So you can take care of akumas, Adrien, while I'm gone."

"I only can hope these people can trust me. I don't want to go through all the hoops we had to jump through to make them trust us all over again."

"Me neither." Marinette paused, a light frown tugging at her face. "You know what we need?"

Adrien nodded, glancing at her. "Ladybug. And Chat Noir."

"Yes! If we talk to the news, they'll have to trust us! The new us, anyway." Marinette clapped her hands, excited.

"We'll have to be careful. We also have to mention the fact that you'll also be leaving Paris sometime soon." Adrien mentioned, frowning.

"I bet I could ring up Nadja and ask if we could place an announcement."

"We should wait a day or two until the news goes around town of these new super heroes." Adrien suggested, beginning to get a little excited.

"For the next few days, Lady Noir and Mister Bug should be the ones doing patrols." Marinette decided. "That way the sight of us is more familiar."

"Hey, don't you mean Mister Bug and Lady Noir? I am, after all, the leader now."

"Chaaaaat." Marinette complained, drawing out the word.

"M'laaaaaaaady…" Adrien mimicked back, rolling his eyes. "Relax, it was a joke. But I agree with you. Should we go our normal way, or a different route?"

"You're the leader now, aren't you?" Marinette challenged, smirking at him.

Adrien moaned softly, glancing sideways at her. "Really?"

"You brought this upon yourself, Adrien." Marinette teased, winking.

"You're the worst girlfriend I've ever had." Adrien decisively announced, scowling at her.

"And only girlfriend, which automatically makes me the best, as well." Marinette leaned against his shoulder, and could feel him deflate, wrapping an arm around her to hold her tighter against him.

"You're right about that." He smiled, a low rumble in his throat.

The two heroes had learned that, at a certain time tiny effects of their Miraculous wore off on them. After nearly two years of having the Ring of the Black Cat, Adrien had begun to purr involuntary whenever he was happy. Marinette, while hosting the Ladybug Earrings for the same amount of time, began to feel her knees bend whenever she got nervous. It was that small ladybug part of her trying to release poison from her leg joints, but such an effect only actually happened when she was transformed and was being ruthlessly mauled. (That accident with Plerana - a plant akuma - was when she first experienced such a strange effect, and she now had a scar embedded in her back from the adventure.)

Now, as Adrien purred, Marinette found herself leaning further into his arms. "Silly kitty." She mused, laughing.

Adrien forced himself to purr louder, chuckling to himself at Marinette's expression, his girlfriend's originally pleasant face going from cheerful and thoughtful to looking like she knew he was trying too hard.

"No kiss for you, Adrien." Marinette hummed.

Adrien fake-hissed, but, before he could speak, Alya and Nino suddenly appeared in their line of view, speeding up to catch their two best friends.

Marinette and Adrien had previously left their friends behind at the louvre because Adrien 'wanted to show Marinette something'. The words had been an excuse to get away with Marinette to make the announcement, however. 'After I show her we're heading out' Adrien had finished to avoid Nino and Alya looking for them later on.

Turns out, that planned failed seeing as how their two friends were struggling to catch up.

"Marinette!" Alya panted, out of breath.

"Adrien!" Nino said, appearing on their other side, shaking his head.

"You two are fast walkers!" Alya huffed.

"Just show them the video." Nino groaned, clutching his head with his hand.

"Oh~!" Alya squealed, pulling out her phone and holding it out, a play button in the middle of the screen.

Adrien hesitantly pushed it, already guessing what it was.

The super-couple pretended to be surprised when Mister Bug shouted out his oath to the people, and Lady Noir hung back shyly, smiling lightly at the crowd.

It was amateur footage, as could be expected from such a long distance, but clearly Alya had taken it, since there was no other possible way she could have collected it so quickly.

Honestly, the whole reason Marinette and Adrien had chosen the louvre was because Alya had been there at the time.

"That's amazing!" Marinette gushed, staring at her friend once the video ended. "New superheroes to defend Paris!"

"Hmm. Aren't they a little too…new to be battling the advanced akumas that Hawkmoth sends?" Adrien ventured cautiously, playing dumb.

Marinette elbowed him. Hard. It was enough to make him squeak, and glare at her like a hurt cat.

She ignored him, pretending that she hadn't even touched her boyfriend when Alya and Nino gave the two of them confused looks.

"What if Hawkmoth takes advantage of their inexperience?" Adrien wondered aloud, before Marinette posed her elbow again.

Adrien let out a small squeak, worriedly looking at the ready-to-attack joint.

"Rena Rouge, Carapace, and Queen Bee can help Mister Bug if he has trouble. They're more experienced at this then he is." Marinette quipped, her look daring Adrien to argue.

Marinette missed it, but Adrien mouthed Help me! to the couple who stood parallel them.

Alya and Nino exchanged a look and shrugged at his silent plea. But, being the two good friends they were, they decided to help him.

"So, who's house are we going to study at?" Nino asked, glancing at his school bags.

"Wait, I thought we weren't going to study together until tomorrow…" Marinette mused, checking her phone'd calendar, ruining Nino's weak inquiry.

"Um…yeah, Dud- uh- Marinette! I was asking about yesterd-I mean tomorrow!" Nino's nervous excuse came out rushed, his eyes widening as his girlfriend sighed.

Adrien decided that he really shouldn't ever ask his friend for help ever again. He was so bad at dishing it out.

"We're studying at Marinette's. Obviously. We gotta live it up until she leaves! She'll be gone all summer."

"Designer School, right?" Nino recalled, thinking back to it.

"That's right!" Alya praised, grinning. "I can't believe how many major cities you'll be going to. Rome, New York, Moscow, London-"

"-Cairo, Hong Kong -" Marinette continued.

"-Mexico City, Sydney." Adrien finished.

"You're also going to Seattle, right?" Nino asked thoughtfully, looking down at his former-crush.

"Yep. That's less major, but…" Marinette shrugged. "You know."

Adrien's phone suddenly beeped, and he looked down at it in surprise. "Aw, dang it. I need to head home for a Chinese lesson."

"Oh, man, bad luck." Nino sympathized.

Adrien, in such a low voice that only Marinette could hear, mumbled "soon that luck will reverse."

Marinette snorted, holding back an outright laughter, shaking her head.

"You'll be free tomorrow, right?" Nino asked, hoping against hope that he would be.

"Note why we're studying tomorrow." Adrien winked. "At Marinette's, remember that."

"Oh, don't worry, Adrien." Alya reassured him. "I'll make sure he remembers."

Adrien nodded, a sharp pain squeezing in his heart as he though of Marinette leaving Paris for a full nine weeks. How would he survive without her patient guidance?
