Hermione fought the very air around her, leaning into the bitter wind and staggering forward towards the public Apparition point. When she'd been inside her cozy flat only five minutes ago, the weather had been beautiful. Crisp snowflakes falling from a soft cloudy sky.

Then she'd decided she'd go for a bit of a walk, like a bloody idiot. She was of half a mind to go home, tell Tony to forget it, and take a hot bath.

She sighed. As if she could deny Tony anything, much less time spent just the two of them doing something as domestic as decorating a Christmas tree. If she knew one thing about herself, it was that she was incredibly bossy. If she knew a second thing, it was that she was disgustingly in love with her best friend and would bend over backwards to make him happy.

Besides, it was only another block to the Apparition point. She was closer to there than she was to home at this point.

Four minutes and a turn on her heels later, Hermione found herself in the common area of Avengers Tower. The music – Twisted Sister's Silver Bells, if she was correct, a Christmas favorite of Tony's – was loud enough that Tony didn't notice the pop of her appearance, and she took a moment to watch him sort through the boxes of ornaments and tree decor before him.

He was sitting cross-legged on the floor and had red and gold tinsel wrapped around his neck in a mimicry of a feather boa; somehow faux-snow flocking had made its way into his hair, mirroring the very real snow in Hermione's own. His brows were furrowed in concentration and dark circles decorated under his eyes. She wondered if he'd been sleeping enough. Probably not.

"Getting started without me?" she called as she approached, projecting her voice enough that he could hear her over the music.

"JARVIS," he said without looking away from the box in front of him, "turn the tunes down. Granger, get over here and help me figure out how the hell a Christmas tree works."

Smiling, Hermione took his hand and helped him up to his feet. "Alright, alright, let's get this festive monstrosity under control."

Together, they worked to untangle the tree's branches and fluff them out, giving it a more natural shape. Hermione expertly placed the ornaments, ensuring each one had its own special spot. Tony, having recovered from his initial frustration, now seemed to be enjoying the process, his eyes lighting up with each ornament he placed.

As they worked, they exchanged stories of Christmases past, their voices weaving together like the lights on the tree. Tony regaled her with tales of extravagant Stark family celebrations, while Hermione shared memories of cozy Christmases spent with the Weasleys at the Burrow.

Gradually, the tree began to take shape, transformed from a chaotic mess into a proper symbol of the season. The lights twinkled merrily, reflecting in the ornaments and casting a warm glow on their faces. "Those string lights look damn fine," Tony said, clearly satisfied with their work.

"They're called fairy lights."

Tony stuck his tongue out at her and she resisted imagining what that tongue could do, exactly.

Finally, when the last ornament was placed, they stepped back to admire their handiwork. The tree stood tall and proud, a testament to their combined efforts. Hermione sighed. "It's beautiful."

Tony didn't respond for a moment; when she turned to him, he was just… looking at her. "You're beautiful, all lit up by Christmas lights, you know."

Her heart skipped a beat. She'd been dancing around her own feelings for months, trying not to let on that she felt more for him than simple friendship – was it possible he felt the same? Normally she'd have written off his words, but something in his eyes was different than any time he'd mindlessly flirted with her, something deeper was there. A determination took root within her.

Taking a deep breath, she leaned in and held his gaze. Their lips were inches apart, their breath intermingling, the only sound in the room Pastor Brad's quieted rendition of What Child Is This.

Then, slowly, their lips met and her eyes slid closed. It was a hesitant touch at first, a tentative exploration of uncharted territory. But as they melted into the kiss, all the unspoken words, all the longing and desire, finally found their voice.

The kiss deepened, fueled by months of pent-up emotion. It was a kiss of stolen glances and it tasted of fine whiskey and Christmas magic and the promise of something more.

When they finally pulled away, their chests were heaving.

"They're called fairy lights," she reminded him.

"Merry Christmas, Granger," he replied, his smile mirroring her own.

And as they sat there under the twinkling fairy lights of the Christmas tree, Hermione hoped that this was only the beginning of their story.
