Adventure might be another theme. Imagine a story where a group from Iceland and Hong Kong go on an adventure together, perhaps exploring some mysterious place. Also, friendship could be a central theme, showing how people from these two different regions form deep bonds.
I really liked 'Unlikely Bonds'. In this fanfiction, it delves into how Hong Kong and Iceland, despite coming from very different backgrounds within the Hetalia universe, find common ground. It's full of sweet moments and interesting cultural exchanges that are presented in a really creative way.
One popular Hetalia Iceland x Hong Kong fanfiction is 'A Nordic - Asian Encounter'. It focuses on the cultural differences and similarities between them. It has a really interesting plot where they start as strangers and gradually develop a deep friendship which might turn into something more.
Archive of Our Own (AO3) is a great place to start. It has a large collection of Hetalia fanfictions, and you can easily search for Iceland x Hong Kong ones using the search bar. Just type in the relevant tags like 'Hetalia', 'Iceland', 'Hong Kong' and it should bring up relevant results.
Fanfiction.net is another place to check. There are many Hetalia fanfics on there as well. However, the tagging system might not be as precise as AO3, so you might need to do a bit more digging. But it's still a good resource.
Well, it's a rather unusual pairing. Fanfiction often depends on the creativity of individual writers. Maybe you could join some international fanfiction communities or forums where people might share or discuss 'Iceland x Hong Kong fanfiction'. However, keep in mind that the amount of such content might be limited compared to more common pairings.
There could be a fanfic where a character from Hong Kong travels to Iceland and has an encounter related to lemons. Maybe it's a story about a chef from Hong Kong who goes to Iceland in search of unique ingredients and discovers a special lemon - based recipe there.
A love story might be set in this fanfic. A Hong Kong native meets an Icelander during a trip. They bond over their shared love for lemon - scented things, like lemon tea or lemon - scented candles. Their relationship develops as they explore both Hong Kong and Iceland, learning about each other's cultures along the way.
A story where a Hong Kong entrepreneur visits Iceland to explore business opportunities in the renewable energy sector. In Iceland, they meet an environmentalist who is passionate about protecting Iceland's natural resources. Together, they come up with a plan to bring some of Iceland's sustainable practices to Hong Kong, while also respecting the unique cultures of both places.
The music cultures could be combined. Imagine a Hong Kong pop star collaborating with an Icelandic singer. In the fanfic, they could meet at a music festival and decide to create a new song that combines the energetic beats of Hong Kong pop with the ethereal sounds of Icelandic music. They might also share their different songwriting techniques and performance styles, creating a unique musical experience that represents the blend of both cultures.
