I'm not sure if there is such a fanfic specifically. Fanfiction can cover a wide range of scenarios, but this particular one might be a bit controversial in the context of the 'How to Train Your Dragon' fandom. It could exist in some corners of the fanfiction world, but it's not a common or widely known plot that I'm aware of.
If such a fanfic existed, it would probably shock a lot of fans. The relationship between Astrid and Hiccup is quite iconic in the 'How to Train Your Dragon' series. This would change the perception of Astrid's character and also add a lot of drama to the fan - created narrative. It could also lead to a split among fans, with some being interested in this new, darker take on the relationships, while others would firmly reject it.
In 'foolish x eret fanfic', the fact that they both exist in the same fictional universe gives a lot of room for creativity. Writers can explore their backstories, how they met, and what their future could hold. Their interactions, whether it's friendly banter or deeper emotional exchanges, can be really engaging for readers. Also, the fanfic can introduce new scenarios and adventures that we might not see in the original content, which is always exciting.
I'm not sure exactly which 'foolish x eret fanfic' are popular. You could try searching on some fanfic platforms like Archive of Our Own. There might be a variety of stories there written by fans.
One possible fanfiction could be about how Hiccup and Astrid deal with the pregnancy. Hiccup might be overprotective, constantly worried about Astrid and the baby. Meanwhile, Astrid could be trying to keep up with her normal Viking duties while also preparing for motherhood. And the lemon element could be a symbol in the story, perhaps it's something Astrid craves during her pregnancy, leading to some humorous or heartwarming scenes between her and Hiccup as he tries to find the perfect lemon for her.
Astrid might initially be in shock. She could just stand there, frozen, unable to believe that Hiccup is really gone. Her eyes wide open and her body trembling as she tries to process what has just happened.
There could be a mean - spirited colleague named Mark. He might constantly make snide remarks about Astrid's work or appearance, which would add to her discomfort. Another character could be a nosy neighbor, Mrs. Thompson. She always pries into Astrid's personal life, asking inappropriate questions and making Astrid feel awkward. And then there could be a clumsy acquaintance, Jake, who always seems to get in Astrid's way and cause embarrassing situations for her.
You can describe her physical appearance. For example, 'Astrid's usually bright eyes were dulled, with dark circles underneath them like smudges of soot. Her shoulders drooped, and every step she took seemed to require more effort, as if her boots were filled with lead.'
