The race for the most tear-jerking Christmas ad is officially on - and a Norwegian postal service might just have won it.

In their festive ad, Posten - Norway's national postal service - delivers an emotional twist on the tradition of children waiting up for Santa.

But rather than an excited boy or girl waiting for their present to be delivered, we follow Santa's lonely boyfriend as he waits all year to spend one night with his bearded beau.

Playfully titled 'When Harry Met Santa', the short film celebrates the Christmas spirit as well as nodding to Norway's 50 year anniversary of decriminalizing homosexuality, which it will mark in 2022.

We start off with a shirtless Harry glimpsing Santa as he disappears up the chimney. The next year, Santa lingers a little longer, and the following year, longer still. Their relationship progresses slowly - but only for one day a year. In between, we're shown Harry's loneliness as he waits for Christmas Eve.

Eventually, Harry does what all children do before the big day - he sends Santa a letter. But he makes it clear there's only one present he's interested in finding under the tree, writing: "All I want for Christmas is you."

The heart-string tugging conclusion comes when a beaming Posten worked delivers Harry a stack of presents, and he turns around to find Santa waiting in his living room. The two share a rom-com worthy kiss and all becomes clear; Santa enlisted Posten to deliver presents so he could spend more time with his boyfriend.

Unsurprisingly, the advertisement has had people in tears, with many tweeting their love for it.

"Well I'm sobbing inconsolably at this," commented one user. "I'm all here for queer Norwegian Santa," added another.

"How joyous, and likely to annoy the sort of people on Santa's 'Naughty List,'" a third wrote.

Posten said that they were aware the advert might not be to everyone's tastes, but that they stood behind its message of love and inclusivity, Pink News reports.

"There will certainly be some negative reactions from some environments, but we are prepared to deal with that," the postal service said. "The right to love whoever you want is a fundamental human right, and is not considered a political issue in free democratic societies in 2021"

"Norway Post has connected people for 375 years, and will continue to do so regardless of orientation or gender identity," they added.
