Chat Noir angled the phone, smirking in anticipation. He clicked the button, moving to pose differently with each flash from the ghost-shaped frame. "My Ladyyyyyyy!" He called, running over excitedly.

"Yes?" Ladybug did not like that tone. 

That tone meant he wanted something. Or that he was excited about something. And Ladybug wasn't sure just how many more pictures of green-eyed black kittens she could get through before snapping Chat's phone in half, throwing it to the ground, and crushing the remains with her heel before exclaiming, "Whoops! Thought there was an Akuma in there!". 

"Look at this cat-"

"NO!" Ladybug yelled, arms flailing.

"No, trust me." Chat insisted.

"I don't!" Ladybug lied, hopping on her tiptoes.

"You do! Look!" Chat said, forcing the phone at Ladybug's face.

Ladybug squeezed her eyes shut, sure this cat picture was going to crack her. "No!" She whined.

"D-Does wadybug not tw-twust me?" Chat asked, using his best toddler voice.

And his best kitty eyes. And his best sad expression. "No. Don't make me look." Ladybug said, shaking her head as she squeezed her eyes more tightly shut.

"Oh..." Chat said, squeezing out a whimper.

"Wait, are you okay?" Ladybug asked, fooled by the realistic sound.

Her eyes popped open to the sight of Chat's (fake) broken expression. Ladybug, trying to forget the face, shut her eyes again, throwing her palms over top to be safe. "P-pwease?"

"Goddammit!" She said, frustrated, giving in by throwing her arms up.

"Yay!" Chat said, bouncing up and down.

He rushed over behind Ladybug to hold the phone out. Click. "What was that?" Ladybug asked, looking around.

He hadn't been so stupid as to take a picture, had he? But Chat Noir was stupid, so he indeed had. "Hashtag hanging out with bae!" He said, typing at his phone.

"What?" ladybug asked, snatching the phone from Chat.

Adding one snap to your story. A little loading bubble appeared, and Ladybug clicked the banned of information. There was the image, Ladybug looking unimpressed, Chat behind her, smiling lopsidedly. "Ooh let's see how many views!" Chat said, hitting a little arrow at the bottom.

There were loads of names who had seen the image, and plenty had double-arrow-type things next to their names. "Chat!" Ladybug said, trying to grab the phone back.

"What?" He (guiltily) innocently asked.

"Take it down!" Ladybug complained, trying to grab the phone from Chat's long arm.

"Not until you.... try all the filters with me!" Chat said.

"Are you going to add it to your story?"

"Not unless you say I can." Chat promised.

So that was how the two ended up sitting on the Eiffel tower, playing with the filters SnapChat had to offer. "Okay now raise your eyebrows." Chat was instructed.

Ladybug did, and an explosion filled the screen, followed by pixel-made glasses and what appeared to be a joint. These came to settle on Ladybug's eyes and mouth, and she let out a laugh at the ridiculous filter. "When would you need that?" She asked between laughs.

"When someone is being cool." Chat said, as though it was the most obvious thing in the world.

"So you must never use it on yourself, then?" Ladybug asked.

"Ladyyyybuuuuug!" Chat whined.

"Okay, okay. Next one." Ladybug urged.

Chat moved his finger, a filter that simply photoshopped the image of the two into "perfection". "You need to kiss me for this one to work." Chat tried slyly.

"What? What does it do, then?" Ladybug asked, skeptically.

Chat, taking this as positive, continued. "I don't know. I don't let people, other than you, my lady, kiss me." Chat said.

He held his breath. Was this going to work? "On the cheek." He added hurriedly.

"Well, I must admit my curiosity." Ladybug said.

"'Tis undeniable." Chat concurred.

Turning to look at Chat, Ladybug leaned forward. She stopped, an inch from Chat's cheek. "Remind me, why, exactly, should it be me to help you?" Ladybug asked.

Chat turned to face his partner. "What a tease. Don't you want to know what this filter does?" Chat asked.

Now, Chat had fully intended to turn back to smile at the camera. He found this difficult, however, with very soft, very nice, lips pressed to his own. "I already do." Ladybug said, flicking Chat's bell.

What struck him first was not that Ladybug had kissed him, but that Ladybug knew what the filter did. "What does it do?" He asked, dazedly.

"Attempts to make you look better. It doesn't work, apparently. You look the same." Ladybug rolled her eyes.

She turned away, laying flat on her back. Silence. After a moment, "So when are you going to register-"

"You kissed me!" Chat cut in.

"-I kissed you?" Ladybug finished in tandem with Chat.

Chat, overwhelmed, began his fan-girling. "Omg, Ladybug kissed me! Ladybug kissed me! Ladybug kissed me! Ladybug kissed me!" Chat said, waving his hands around.

Ladybug unhooked her yo-yo from her belt, about to take off. She'd expected something less comical. "Wait!" Chat said, grabbing Ladybug's hand.

"What?"

"I.... I love you." He admitted.

How sudden. Ladybug noted. "I love you, too, you stupid cat." And with that, Ladybug zipped away, surprised her heart was still beating, despite clearly using up a lifetime's worth of beats.

"I just kissed Chat Noir."
