A/N: This is the beginning of my Christmas fanfiction project! Basically I'm just going to drown you in OTP fluff. :3

Here's the first chapter of this series, involving what I call Eternityshipping (although technically officially called Possessshipping) which is Judai Yuki x Johan Andersen x Yubel.

Yubel doesn't know what Christmas is, and cannot understand the point of having a pine tree in the middle of the room. Perhaps the boys can enlighten her on this Christmas tradition?

Please enjoy!

Johan would not stop humming.

Normally, this wouldn't bother Yubel, as she was used to Johan's cheerful antics and often actually enjoyed them. But he had been humming the exact. Same. Song. For about the past hour and a half as he bustled around the house.

She folded her arms, leaning against the wall and feeling disgruntled.

Johan's house wasn't very big, just a simple one floor building. It felt warm and cozy though, and was a comfort from the tent she and Judai had been sleeping in for the past three weeks. It was getting colder out, though, and even Judai wasn't keen on the idea of long-term camping in the snow. They happened to be in Eastern Europe at the time, so Judai had suggested crashing at Johan's place. Yubel was only too happy to agree.

"Besides..." he had said. "It's getting to be that time of year again, isn't it? Wouldn't be too much fun to spend it alone..."

Yubel wasn't sure what 'that time of year' was, but if it got Judai out of the cold and into a place where someone was sure to make him eat, she was all for it.

Judai was probably currently perched on the couch where he had been all day, probably still looking a little miffed that Johan hadn't wanted him to help with cleaning up the house.

"Johan, are you sure you don't want me to help you out with anything...?"

"Nah, you two have been traveling for quite a while, so just relax for a bit! Don't worry, I'll put you to work helping me with the lights on the tree later."

Lights? On a tree? Yubel snorted. It must be some kind of joke. She phased through the hallway wall to come out into the living room.

It was a small, but warm affair. The deep brown maroon carpet and dark wood-paneled walls soaked in the yellowish light from the hanging ceiling fan, giving the room a dim but warm ambience. A fireplace sat on one side of the room, and it was currently dancing with a warm, toasty fire. Above the fireplace hung what appeared to be very huge socks. Interesting. She doubted those would fit Johan, but why would they be hanging over the fire? Had they gotten wet?

"Actually, Judai, could you come here a second?" Johan called from the kitchen, where he had already bustled himself off to.

"Sure," Judai said, jumping up.

Yubel remained in her ethereal form in the living room, still confounded by the socks. They didn't seem to match each other, and there were only three of them. One was a bright red, another one blue, and the last one a deep royal purple. What on earth were they for? It was just about as mystifying as the pine tree sitting in the corner of the room. Sure, it smelled nice, but what on earth was Johan thinking bringing a tree inside his house? She didn't get it at all.

She was busy staring at the tree and trying to divine its purpose when Johan and Judai returned from the kitchen. Judai was hefting a pair of cardboard boxes, and Johan had some clear containers that seemed to be full of round, shiny objects.

"Ah, Yubel! We were just going to put the lights on the tree, do you want to help?"

"Lights...?"

"Yeah! We're decorating! For Christmas!"

"And that is...?" Yubel said, raising an eyebrow.

Johan sent Judai a sidelong glance. Judai smiled, a bit embarrassedly.

"What, you haven't explained it to her yet?" Johan said. "Come on, Judai."

"It just didn't come up?" Judai said, shrugging and blushing a bit. "Besides, Christmas in Japan...well, it's a lot different, kinda...never mind, Johan, you're better at explaining things anyway. Where do you want these boxes?"

He didn't wait for an answer, setting down the boxes next to the tree. Johan rolled his eyes.

"Geez. Both of you. This is why I worry when you two are on your own."

He sighed. Then he looked up at Yubel and nodded.

"Christmas is a holiday," he said. "It's mostly a Christian holiday about the birth of Jesus, I guess...but quite a lot of people celebrate it."

"The tree is a part of this?" Yubel said. "What purpose does it serve?"

"Hell if I know," Judai said. He had opened the box and was pulling long cords of green stuff with little colored bulbs on it. "How do I do this again?"

"Yeah, I don't really know what the tree is for either," Johan said, laughing. "It's just a tradition. You get a Christmas tree, and you decorate it with lights. Well, technically here we usually wait until Christmas Eve to do it...but when I heard you guys were coming I really wanted to decorate early."

He padded over to Judai and took the string of lights from him, demonstrating how it was to be wrapped around the tree. The two boys started getting the lights into place.

"It's just a winter tradition, then?" Yubel said. "You seem awfully excited about it."

Johan laughed.

"I've always loved Christmas," he said. "It's just such a cheerful time of the year. And this year, I get to spend it with both of you...that makes me really happy."

Yubel found a smile coming on. Well, she still didn't get it. But it was making Johan pretty happy, and even Judai looked like he was getting a smile on his face working on the tree. She breathed out.

"Well, if it something that you like...I guess I'll have to participate too," she said.

She floated over to the tree. Judai smiled, and tapped the card locket around his neck. It only took a second for the spell to take hold, and then Yubel and Judai were temporarily separated and she had a physical presence again. With a smile of gratitude, Yubel joined in the tree wrapping. It still seemed very, very silly to her to put lights on a tree...

About halfway through the project, Johan paused to run over to the stereo and put a CD in, claiming that you couldn't decorate the tree without Christmas music. It wasn't long before Yubel was well-acquainted with the songs that Johan had been humming – but they weren't quite as annoying as she had thought before, so it was all right.

"Done!" Johan said, stepping back and nodding. "That went so much faster than usual."

"Let's get them plugged in," Judai said.

He knelt down by the wall and pulled the cord over to the outlet. The moment the plug thunked into place, Yubel drew in a breath.

Beautiful lights glowed from inside the frames of paine branches: red, green, blue, glittering softly against the shadowy pine needles. It was...beautiful. She hadn't thought something so odd could be so gorgeous but...

"It's beautiful, right?" Johan said quietly.

He had stepped over to stand on one side of her. Yubel nodded, still staring at the lights. Smiling quietly, Judai came over to stand on her other side, his hands in his pockets.

"I guess I didn't really explain cause I thought it'd just be more fun to experience," he said, rubbing one finger under his nose. "You like it?"

"Yeah," Yubel said.

Quietly, she slipped one hand into Johan's, and the other into Judai's. They squeezed her hands back.

"We should do ornaments now," Johan said.

"Ornaments?" Yubel said.

"Yeah!" Judai said, breaking away and opening another box and pulling out a small red orb on a hook. "We hang these on the tree next."

"That sounds silly. Why would you hang things on a tree?"

Judai and Johan exchanged grins.

"Oh, she's gonna love this," Judai said.

"Just wait til you see the tree when it's done," Johan said, squeezing her hand again. "Don't worry. This Christmas...I think you're really going to enjoy it."

She smiled. She couldn't help it – the boys' cheer was contagious.

"I suppose I'll have to," she said. "If you two numbskulls have anything to say about it."

She pulled a red orb from the box, balancing the hook around her finger. She looked up at the tree, with its glittering lights, and then down at the small shiny sphere, which reflected the lights in its surface.

She smiled.

Perhaps it wasn't such a silly tradition after all.
