They can distort it. Since the original Bnha series is about heroism, friendship and growth, 'bnha abusive class fanfic' which often involve negative themes like abuse can make some readers see the characters in a different, darker light. It might make them question if such negative aspects could potentially exist in the original world too.
One interesting BNHA Class 1B fanfic could be 'The Rise of Class 1B'. It focuses on how the students of Class 1B work together to overcome challenges that are often overlooked compared to Class 1A. Another is '1B's Secret Missions' which delves into the special and unique missions that only Class 1B gets assigned. And then there's 'Class 1B: Bonds Beyond the Classroom' that explores the deep friendships and rivalries within the class.
The Bnha universe's reaction would be mixed. Those who are into complex stories, like Todoroki, might study the relationships in Hamilton fanfiction. But others, like Mineta, might not be interested at all because it doesn't have much to do with his usual interests. Overall, it would depend on the individual characters' personalities and interests.
One popular 'bnha abusive class fanfic' might be those that explore how the class environment turns toxic due to a particular character's actions.
