"Caitlin," Barry practically whined, his tone and demeanor defeated, "what do you want?"

The doctor shook her head for what felt like the millionth time that day. "Barry, I told you," she said, looking at him pointedly. "I don't want anything for Christmas."

"But I have to get you something," he insisted. "It's our first Christmas together with, you know, us actually being together." He sighed, putting his hands on his hips. "I want it to be special."

Her lips quirked upwards, her eyes softening as she stepped into his personal space, wrapping her arms around his lean frame and burrowing her head underneath his chin. "Just being with you will make it as special as it needs to be," she told him, squeezing him just a little bit tighter afterwards to help get her message across.

The tension in his body released, contentedness instead spreading through his bones as he held her just as tightly back. His lips pressed into her hair, his nose instantly picking up the cherry scent of her shampoo, easing him into an even more serene state as he nuzzled his head down against hers. "You're all I need too," he told her, "but that still doesn't change the fact that you already gotten me a present though. It feels unfair that you wouldn't get one."

She detached herself from her position enough to look him in the eye. "Yes, but I got that gift for you before we were together. I got it back in April."

He shrugged. "Still, I want to get you something. You said not to get you any jewelry or anything too expensive, so I don't know what else to get you."

Her hands reached up, threading themselves into his thick hair. "If you must, I'm sure that pretty head of yours will think of something."

"You think I'm pretty?" he asked, smirk stretching along his lips, his hands discreetly slipping under her blouse and brushing against the bare skin there.

Caitlin's eyes grew a tad darker. "Very pretty," she confirmed, her own hands wrapping themselves around his neck before leaning up and pressing a searing kiss against his mouth.

"Mmm," Barry hummed out pleasantly against her lips as they stopped for air. "So, what do you want for Christmas?"

Her head shot back. "Barry!" she hollered, annoyed, as she detangled herself from her boyfriend to go back to her computer.

"Oh, don't act like that wasn't you trying to seduce me to forget about your present."

Her posture straightened. "I would never do such a thing."

Barry snorted. "You never let us fool around at the lab. Why would you suddenly be okay with it now?" he asked, looking down at her deliberately, knowing he was right, especially when she refused to look him in the eyes.

"Can you please just drop it?" she asked, pleading with him.

"I will," he told her, and she sighed in relief, "if you tell me something to buy you."

"Urghh," she groaned, closing her eyes in frustration. "Fine! Fine!" she hollered. "Get me a...unicorn!"

Barry scrunched up his face. "Unicorn? Wouldn't that be considered expensive?"

"I imagine they would be," she said, "you know, if they were real."

He rolled his eyes. "Come on, Cait. Be serious here."

"I am being serious. I told you what I want. Stop asking."

Barry let out a huge breath in defeat. "Fine, fine. But you'll be the one laughing when I get Cisco to find an Earth where unicorns exist!"

Caitlin merely rolled her eyes and ignored him.

…

Caitlin woke up to the feeling of someone combing their fingers through her hair. Knowing it could only be Barry, she sighed out blissfully. "Merry Christmas," she mumbled as she groggily opened her eyes, her heart catching at the sight of him, in bed, next to her. She still couldn't believe she got lucky enough for this to be her life now.

"Merry Christmas, sleepyhead," he greeted, an amused but adoring smile pulling at his lips before he leaned down to press a small kiss on her lips.

"What time is it?" she then asked..

"11am."

Her eyes bulged; she never slept in that late. "Why didn't you wake me up sooner?" she wondered, unsuccessfully fighting back a yawn.

Barry chuckled. "Because you don't get enough sleep as it is," he told her, reaching out to caress her cheek. "Think of it as a Christmas present."

"Mmm," she hummed out, contently leaning into his warm touch. "So no unicorn, eh?"

He smirked, his eyebrows playfully jumping. "I didn't say that," he said as he got up from their bed and jogged out of their room.

"Please don't tell me you brought a unicorn into our apartment!" she hollered, sitting up in her bed.

She heard him let out a hearty laugh from down the hall, which did not ease her suspicions one bit. While Barry was usually a rational guy, sometimes his romantic gestures knew no bounds.

A moment later, he came back in with a bag that had snowflakes on the side and was filled to the brim with red tissue paper. He jumped on the bed and gleefully handed the present to her. "Open it," he told her excitedly.

She eyed her boyfriend, finding his childlike enthusiasm adorable, but it nevertheless left her apprehensive. She quickly plucked the tissue paper out of the bag to eventually find, not only a stuffed unicorn, but a stuffed unicorn dressed in a Flash costume. She giggled as she took it out.

"The red costume kind of clashes with his colorful hair," she joked, her fingers teasing through the unicorn's rainbow-colored tail.

Barry chuckled. "You can take the outfit off," he told her. "But when I saw it as an option in the Build-a-Bear store, I couldn't not get it, you know?"

Caitlin held the animal against her chest, lightly hugging it. "No, I love it. It'll remind me of you even more when I look at it."

The speedster smiled, his eyes watching her affectionately. "And if for whatever reason I'm out of town, or you just need to hear it…" he said trailing off so that he could squeeze the unicorn's paw.

A voice then spoke from the bear - Barry's recorded voice. "I love you, Cait."

The doctor immediately locked eyes with her boyfriend, her eyes growing watery at the rush of affection and joy that was coursing through her. "I love it," she told him, holding the animal even closer to her before reaching over and kissing Barry tenderly.

"I'm glad you like it," Barry said as they seperated. "I know you weren't serious when you told me to get you a unicorn, but..."

She giggled. "It's perfect, honestly. But I guess this means you and Cisco couldn't find an Earth with a unicorn then?"

Barry shook his head. "Actually, we found some on Earth 13, but, believe it or not, unicorns are not the friendliest creatures in the multiverse…"

"Oh?"

"Let's just say that it was a good thing I could run fast," he admitted with a chuckle. "So it seemed like the safer option to go with the stuffed animal, plus it's more practical to have than a real one."

"Way more practical," she agreed with a lazy smile, her face gravitating towards Barry as they shared another kiss, which he had no complaints about. "And definitely safer, since I doubt Snowbarry will be attacking anyone anytime soon."

Barry raised an eyebrow, his lips pursed as he tried not to laugh. "Snowbarry, huh? That's the name you're giving it?"

"I think it's cute," she said with a playful pout. "It's a mesh of our names, and it sounds adorable and magical like unicorns are supposed to be."

His eyes crinkled as he looked at her with soft, tender eyes. "You're cute," he told her, taking the stuffed animal out of her hands to set it aside. He then crawled on top of her, making her lie back down on their bed. "And you're adorable, and magical, and simply an amazingly beautiful being," he spoke in between peppering kisses along her neck. He then lifted his head to look straight in her eyes. "And I love you," he told her sincerely.

Her hands reached up to trace his face, her chest constricting with how much love, care and devotion she had for this man. "I love you too," she told him back wholeheartedly before guiding his face back down to hers, but eventually ending it with a groan. "We have to meet Cisco and Cynthia soon; I have to start getting ready."

Barry jumped to his feet, tugging at her hands to help her up. "Then let me help you with that," he said suggestively with a playful smirk, leading a giggling Caitlin to the bathroom.
