Another plot point could be that Hiccup has to go on a dangerous mission alone. Astrid, worried sick, decides to follow him secretly. When Hiccup discovers her, at first he's angry but then realizes how much she loves him. This moment of realization could be a turning point in their relationship, and they could have a more open and affectionate relationship from then on.
A plot point could be a misunderstanding. Maybe Astrid sees Hiccup spending a lot of time with a new female dragon rider and gets jealous. This causes a rift between them, but then they have to work together to save Berk from a new threat. During this, they clear up the misunderstanding and their love becomes stronger.
One interesting plot idea could be Hiccup and Astrid going on a secret adventure to a new, uncharted island. They face new dragons and have to work together to survive. Another could be a story where they have to deal with a rift in their relationship due to a misunderstanding, like Astrid thinking Hiccup is spending too much time with a new dragon rider. A third idea is a time - travel plot where they go back in time and have to change something in Berk's history to save the future.
Another interesting plot point could be a misunderstanding. Maybe Astrid sees Hiccup with another girl (who is actually just a friend helping with dragon research). Astrid gets jealous and starts to distance herself from Hiccup. Hiccup is confused at first but then realizes what's going on and has to work hard to win Astrid back. This creates a lot of drama and tension in the story.
There's also 'The Bond of Hiccup and Astrid'. This fanfiction takes a different approach. It focuses on their love through small, everyday moments. For example, how they train their dragons together and steal glances at each other. It's a very sweet and simple story that really shows their deep connection.

One idea could be exploring how they adjust to the new responsibilities. Hiccup might be worried about protecting his family while still leading the village. Astrid could be determined to train their future child to be a great dragon rider from an early age.
One great fanfiction could be 'A New Beginning'. It explores their married life as they face new challenges in Berk. Another is 'The Married Adventures' which focuses on their daily life and how they grow together.

I've also come across 'The Hidden Cove'. Here, Hiccup and Astrid discover a secret cove. The story delves into their feelings for each other in a more secluded and romantic setting. It's a really engaging read.
The popularity of 'HTTYD Hiccup and Astrid Love' fanfictions is due to the strong base of their relationship in the original series. Fans love to explore more of their love story. They are a very dynamic couple.
