He usually prided himself on keeping a cool exterior, but as he ascended those stairs and awaited his Blair, he was anything but. He wasn't nervous, he was excited, giddy even.

Then Bach started playing and he cracked a quick chuckle. She was full of surprises.

"You're so calm Blair bear, I am impressed." Harold said as he took her arm. "Well, there's nothing to be nervous about. Not today. Not with Chuck"

"We've all known for a long time, it's just wonderful that you've both realized it, too," Harold smiled.
"What's that?"
"You're soul mates dear." Cyrus said grabbing her other arm.

"Oh! There's the Bach!" Serena turned around and gave Blair a knowing smile before walking.

Many years ago...

The four of them were crowded around at one of their parents' incessant soirees, though Chuck was solo as usual since Bart was away on business. They were practically invisible to the adults and their cocktails, so the nine year old kids sat there and ate petit fours and drank champagne in another room thanks to Chuck and his classic knack for the sneak.

As he was coming back from the bathroom, he saw Blair's mom yelling at her in the corner yet again about her figure.

When she walked away, Chuck couldn't watch Blair cry so he went up to her, brought his hands to her face and wiped her tears. "Your mom is an idiot, she doesn't know you."

She would never admit it, but Chuck was her best friend. Though heavily inappropriate most times, he was always protecting her.

"And you do?" She said sarcastically.

"Better than you think, Waldorf." With that he grabbed her hand and sat down at the piano back in another room away from everyone and pulled her down to sit next to him

He opened the key case and started playing... Beautifully.

She was in awe of him at that moment. She loved Bach and he knew. She always begged him to play when they were hanging around, but he always waved her off, saying it was part of his silent and solo brooding. But not today.

She sat there, head on his shoulder, closed her eyes and just listened. Neither of them noticed the crowd of people, including their two friends, which had followed the wonderful sounds emanating from the room and formed at the frame of the door.

Nate and Serena never understood how it came to be that Chuck and Blair had this deep, dark unspoken bond, but this wasn't the first time they found them like this and they were sure it wouldn't be the last. It's like they spoke to each other's soul without really even saying anything.

When Blair took her first step and saw him down the aisle, her breath hitched. It was like a domino effect the few people in attendance had their eyes on Blair and quickly turned their heads to glance at Chuck to see the look on his face which was practically stunned at the sight of her. They were magnetic.

She looked like an import from Paris in the 20s, with an extraordinary delicate fitted gown hugging her frame, beaded from chest to floor. Her hair was swept up so that the nape of her neck was visible, a crutch of Chuck's. And there in those chestnut locks, lay a dainty row of vintage aqua crystals in her hair.

She smirked to herself, an ivory tuxedo, with a hint of something blue; leave it to Chuck to match her without even realizing.

As she reached the end of the aisle and was kissed by her dads, he took her hand in his, but not before she wiped the tear from his cheek, and that was that.

"Bass..." She whispered

"Waldorf..." He whispered back.

"Not for long..." She smiled at him.

He was about to say something and just stopped and grinned back.

Lost in the moment, the priest had to clear his throat to get their attention and everyone laughed.

"Sorry father," Blair quipped with a smile.

"That's quite alright dear..."

They floated through the ceremony, listening to readings by Lily and Eleanor, lighting the unity candle with the help of Nate and Serena, they even lit a candle in the chapel for their baby, and exchanged traditional vows before placing platinum bands on each other's finger.

Ladies and Gentleman, I now present to you Mr. and Mrs. Bass

In true Chuck Bass style he had his hands in his wife's before the priest even finished his announcement and was kissing her not even a second later.

With the cheers and claps from their family going strong, Chuck swept her up in his arms and carried her back down the aisle.

A little dramatic Bass, no?

For you, always.

Back at Harold and Roman's chateau, the group dined underneath the stars as a draped tent sat in the fields of their winery. Hundreds of candles and lanterns provided an undeniable air of romance.

Flutes filled with vintage Dom scattered the tables as did lush bouquets of peonies and succulents. Some of their favorite brasseries and bistros along the Seine were to thank for the fabulous fare and the cake was no cake at all, but a tower of pastel macarons from Pierre Herme.

A few toasts occurred. One, from best man Nate who declared, "I am really to thank for this unison after all I did have Blair originally, but was clearly no match to Chuck." And one from maid of honor Serena who said simply "it's really true what they say about little girls and boys that harbor feelings for each other," reminiscing about ripped bow ties and tossed headbands of years passed, due to Chuck and Blair's interesting friendship.

Everyone clinked their flutes and chanted "kiss, kiss, kiss!" at which the couple happy obliged.

Chuck felt the need to say a few words. He planted a chaste peck on Blair's lips before standing.

"You know, I've always thought of myself as an observer, laying on the outskirts and watching everything unfold from afar. Until this lovely lady, showed me what I was missing. She showed me what love was, even if it came with a kick on the shins every once and a while." He paused and shot her a quick smirk.

"I have enough money to buy anything, but what you have all given me is more than I could have asked for, a family. I can't wait for it to grow, but we will never forget what we've lost. So here's to our best friends, our mothers, our fathers, our favorite maid in the whole world, and everyone in between who have stood by our side through it all. And here's to my insatiable wife, the girl who changed me, forever."

Blair rose, tears in her eyes, and kissed him while everyone whistled and clapped, when Moon River started playing.

"You didn't," she whispered

"I did indeed. You can't pull all the surprises, Mrs. Bass. Come on," he said as he pulled her to the dance floor.

"This is going to be great."

"What is?"

"Us."

"It already is."
