It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
One common theme could be the exploration of unexpected relationships. Since mpreg is involved, it often delves into how the characters deal with the non - traditional situation of male pregnancy. For example, how the relationship between Harry and Draco might change due to this new development with Zeke in the mix.
