I based this on Icelandic mythology, Yule. I decided to use the Yule cat because it's my favorite.

Day #5 - Myths and Legends

"No clothes?" Iceland asked once he had finished opening his last Christmas gift. All the Nordics were together to celebrate such important tradition, as well as everyone's partner.

"I don't think so, did you want clothes?" Japan asked the Icelander and he shook his head, not wanting to offend anybody, since all of them had given him a gift.

"No, it's just that I get them every year that it was just normal" he explained and smiled a little at his boyfriend.

But it was true, all his life every single Christmas he would get clothes, not that it mattered to him, but it did feel weird. His brother had given him a watch instead of the usual lopapeysa that always matched his. Denmark gave him a big box of Danish cookies, Finland gave him a new signed knife (for letters) and Sweden gave him a big box of expensive chocolates. His family always had given him clothes and it was weird now that they didn't. But he didn't complain, they were all good gifts.

"Thank you" he said after that and spent the rest of the night laughing and enjoying with his family.

...

"Are you okay?" Japan asked, putting his brand new sweater in the closet. Even though he didn't celebrate Christmas he still went because he knew Iceland did and wanted him to be there.

"Yeah, why?" He replied, a little bit confused at the question.

"You seemed weird earlier"

"I told you, I'm just used to getting clothes all the time, it was a surprise" he said, frowning at the stare Japan was giving him "what?"

"That's not all. What's really happening?" And even if he tried to hide it, Japan knew him very good. His cheeks became red for what he was going to say.

"It's stupid... It's... Hm..."

Japan raised an eyebrow and waited for an answer.

"The yule cat"

"The what?" He asked in confusion, he had never heard such thing.

"The yule cat... Is a legend in my land. If you don't get new clothes for Christmas it is going to eat you"

Japan chuckled, received a bad look from the Icelander. He sat on the bed, next to him and caressed his hand with his thumb.

"Is that what's worrying you?"

"Not worrying... I just thought about that, you know" he replied, looking down. Japan stood up and walked to the wardrobe. He took out a little box, wrapped with a beautiful shade of blue "what is that?"

"A gift for you"

"But you already gave me one" Japan placed it on the bed and let Iceland admire the packaging.

"I forgot to give you this one" he didn't, actually, Norway had told him to get him clothes. He didn't ask why, but if his boyfriend's brother said it with such confidence, it might have been for a good reason.

The island nation didn't hesitate and ripped off the paper and revealed a box, which he opened. It contained a sweater, dark blue with a grey pattern. It was very beautiful. Iceland smiled before looking at his boyfriend.

"You didn't have to"

"I didn't want to lose my boyfriend to the yule cat" he joked and leaned forward to hug the Icelander "merry Christmas"

"Merry Christmas"
