Summary: Tsuna had 24 days to get Hibari into a Christmas mood. He was determined to succeed.

A/N: Here we go. A KHR 1827 advent calendar just for you. Or for me. For fun. I mean… Anyway, since Christmas here in Finland is usually celebrated on 24th, I'm going to make them exchange present on that day too and it means the end of this fanfic. Also, this is going to be so disgustingly cute that I can't. Makes me very jealous of fictional characters of having a better love life than I do, I mean. Ahem xD Yeah, this already makes me want to have someone by my side. Damn you Christmas and damn you HibaTsuna! I'm out. Let's start the countdown.

Day 1

It was a chilly night. December had finally arrived but the streets were still clean of snow, dark and depressing. Couple of decorative lights blinked here and there from the windows of countless apartment house flats. There weren't many lights yet but little by little they would increase and dark streets and grey houses would once again light up, taking depressed thoughts away.

Tsuna let the curtain fall back into its place. Well, the lights lightened almost everyone's mood.

There were still some exceptions. Tsuna frowned for a while, remembering the last Christmas. The very first one he'd spent with his boyfriend in their very own two-room apartment. He'd been excited, Christmas was after all his favourite time of the year. Of course he hadn't expected Kyoya to be on the same excitement level as he was but… frown deepened and the brunet shook his head.

Last year couldn't be repeated.

"I need to do something…" he muttered to himself while letting his eyes wander around the kitchen. It was a small one but cozy. Finally a smile found his lips, the frown long gone. The place held already so many memories he held dear and he knew they'd create more of those in the future. Smile widened. Maybe even this Christmas. Soon the whole apartment would be filled with love, warmth, Christmas carols and a godly smell of biscuits and hot chocolate. Not caring he was already a nineteen-year-old young man, Tsuna bounced on his feet, a plan forming in his mind.

A door creaked open and closed with an almost inaudible thud. A grunt came from its direction which Tsuna translated easily as 'I'm home'.

"Welcome back!" Okay, he had to do this right or else he'd be spending the Christmas night hanging upside down from the sailing thanks to Reborn instead of cuddling with his boyfriend on a couch without a worry in the world. He'd learned the worst way possible that Kyoya was by no means a holiday person. Forcing away his grimace and traumatizing memories, Tsuna smiled the sweetest smile he could muster when the raven came into the room. Kyoya froze on his feet, eyes narrowing in suspicion while he observed the younger man's way too innocent expression. Tsuna blinked, trying to look confused, and slowly his Cloud Guardian took another step towards him. His face stayed the same, though.

Planting a small kiss on Kyoya's lips when he came to greet him, Tsuna then decided it was time to brew some of Kyoya's favourite tea. The ex-prefect sat down, not saying a word since his eyes were enough to tell he didn't trust the atmosphere inside the apartment. When the silence stretched and Tsuna made no intention to start a conversation – he'd gotten quite comfortable with the silence after starting to date the skylark – Hibari finally let out a tired sigh.

"Spit it out, Tsunayoshi. You're hiding something."

And Tsuna could never hide anything from the man. He chuckled lightly, not feeling worried at all when the cold glare intensified. "I wouldn't say I'm hiding anything…"

"Then you're just keeping quiet about it," Kyoya said calmly. "Talk."

The black haired man's arms were crossed while he sat on table. Tsuna brought a hot cup of green tea to him, feeling a blush forming on his cheeks when the smell brought back some memories from their time together. Alone in a reception room after school. Tsuna might have spilled some tea then, once or twice (or maybe even more times than he wanted to admit) and Kyoya had always been the one to help him clean the mess. Now, he placed the violet cup with little pictures of hedgehogs in front of the grown up man and decided that he wouldn't miss this year's Christmas with his loved one. He wanted to be mushy and have fun and kiss his boyfriend silly and Kyoya had better adapt to it.

Tsuna started tentatively. "Do you know what month—"

"No."

"It's Dece—"

"No."

"Well, it sure is!"

"No, it isn't if I say so."

The brunet rolled his eyes at the pouting man. Yes, Kyoya was pouting, not frowning with a healthy murderous intent like he'd once told Tsuna. His lips were pursed, hands still crossed against his lean chest and eyes turned to other direction.

Pouting.

With an amused yet frustrated sigh the young boss decided to let the issue be. For now. He hid his sly grin professionally (Who wouldn't be professional after Reborn's methods of training?) and stood up. The man in front of him let his eyes wander suspiciously to him when he suddenly leaned in and kissed thin lips. At first Kyoya wasn't responding, just pouting and being a moody, dangerous carnivore that he was. After a while of patient waiting Tsuna got the reaction he wanted and made sure to give the deepest kiss ever. Then he drew away, smiling tenderly at an almost invisible blush on pale cheeks.

He'd try again tomorrow. And day after tomorrow and the day after that.

He had whole 23 days left to get Kyoya into a perfect Christmas mood, after all.
