Well, Astrid could be overjoyed right away. After all, she may have secretly had feelings for Hiccup all along. In this fanfic scenario, she might immediately embrace Hiccup and confess her own love, leading to a very sweet and romantic moment between them.
She might be initially shocked. In many fanfics, Astrid is a strong - willed character. So, she could take a moment to process Hiccup's confession. Then, she might feel a rush of happiness and finally reciprocate his feelings.
Astrid could be hesitant at first. Given her tough exterior, she might not be used to such open displays of emotion. She may question Hiccup's motives or worry about how this will change their relationship dynamic. However, as she realizes the sincerity in his words, she may slowly warm up to the idea of loving him back.
One common theme is the overcoming of personal barriers. Both Hiccup and Astrid have their own insecurities and challenges. Hiccup's confession could be a way for them to break through those barriers and become closer. For example, Hiccup might be afraid of rejection due to his past as an outcast, and this confession is his way of facing that fear.
A more light - hearted plot could be set in a modern - day AU (alternate universe) where Astrid and Hiccup are in high school. Astrid has had a crush on Hiccup for a long time, and the fanfic could detail their journey from being friends to finally admitting their love, with all the typical high - school - related obstacles like popularity differences and peer pressure.
One reason could be that the fanfic changes the essence of their relationship. In the original, they have a certain dynamic that she values, and fanfics might mess it up.
