There's a Thin Line Between Love and Hate (Felinette spy au)

She's Mine

The gentle hum of the city filled the air as Marinette and Felix strolled hand in hand down the cobblestone streets. It was one of those rare, perfect days where nothing needed to be done, no one needed saving, and they could just be. Marinette had declared it a "coffee shop kind of day," and Felix, while initially indifferent, couldn't deny that spending a quiet day with her sounded nice.

The midday sun filtered through the trees, dappled light dancing across the sidewalk as Marinette swung their joined hands lightly.

"You know," she said with a smile, "we really don't do this enough."

Felix glanced at her, brow arching. "Do what?"

"This," she said, gesturing vaguely around them. "Regular couple stuff. Walking around, going to coffee shops, people-watching... It's nice to feel like normal people for once."

Felix smirked. "You mean you don't count dodging lasers and infiltration missions as 'regular couple activities'? Shocking."

Marinette rolled her eyes and gave his arm a playful nudge. "You know what I mean. I want to sit in a cute café, sip my latte, and pretend our lives are simple."

"Fine," Felix replied, though the corner of his mouth twitched in amusement. "But if we're ambushed by rogue coffee enthusiasts, I'm letting you handle it."

The café she led him to was one of those hidden gems that only someone like Marinette could find. Mismatched chairs, cozy nooks, and shelves overflowing with books and plants gave it a quirky charm, while the scent of freshly brewed coffee and warm pastries made the place feel like a hug in building form.

Marinette let out a contented sigh as they stepped inside, her eyes lighting up as she spotted the pastry display. "Oh, Felix, look at the croissants! And the tarts! They have macarons too!"

Felix smirked, watching her with amusement. "I see your priorities are firmly in place."

"Don't judge me," she said, sticking her tongue out at him. "You know I'm here for the coffee and the snacks."

"Of course," Felix said dryly, his lips curving into a soft smile. "What would you like, madame?"

Marinette tapped her chin, looking far more serious than the situation warranted. "Hmm... a caramel latte, extra foam, and one of those almond croissants."

Felix nodded, mentally filing away her exact order as if it were classified information. "Could you grab a table while I get the order?"

Marinette smiled, her eyes warm. "Sure. Thanks, Felix."

As he headed to the counter, she scanned the room for a spot, quickly spotting a small table near the window. Sliding into the chair, she let herself relax, soaking in the cheerful chatter of the other patrons and the soft hum of jazz music in the background.

It was peaceful.

Until someone slid into the chair across from her.

"Is that Marinette Dupain-Cheng I see?"

Her head snapped up in surprise, her wide eyes meeting familiar teal ones.

"Luka?" she said, her voice tinged with both surprise and delight.

There he was, his signature calm smile firmly in place, his ever-present guitar case leaning against his chair. Luka Couffaine looked exactly as she remembered—soft-spoken, kind, and radiating that effortless coolness that always made people feel at ease.

"What are you doing here?" Marinette asked, her smile brightening.

"I could ask you the same thing," Luka replied, resting his arms on the table casually. "It's not every day I run into you in the middle of the city."
