Well, it's hard to say for sure. Asgardians have their own rich lore and stories within their own culture. However, if we consider the idea that they could access fanfiction from Earth (assuming they knew about it), some of the more curious or open - minded Asgardians might be intrigued. For example, Loki, who is known for his mischievous nature, might be amused by the wild ideas in fanfiction about him and his family. But others, like Odin who is more traditional, might not care for it at all.
They might be interested because it gives them a different view of themselves. Fanfiction often takes existing characters and puts them in new situations or relationships. Asgardians could find it interesting to see how mortals perceive their powers, personalities, and relationships.
They could be portrayed as shocked. Imagine seeing all those powerful heroes on Earth struggling against Thanos. Asgardians, who are used to their own battles, might be taken aback by the scale of destruction and the power of the enemy.
Well, in some fanfictions, Asgardians might be filled with rage seeing their comrades fall during Infinity War. They could be thinking about revenge against Thanos for destroying their home and killing so many of them.
