They'd be surprised. The more innocent ones like Tsuyu might just blink in confusion. And Todoroki might raise an eyebrow, not fully understanding what it's all about.
Issei could be a bit nervous at first. He might worry about what his classmates will think. But if they show positive reactions, he could become more confident and start sharing more about his writing. However, if they react negatively, he may feel a bit down and might even regret that they saw it.
They might be really shocked at first. Some might find it a bit strange or unexpected, especially Bakugo and Deku themselves. They could end up blushing or getting really embarrassed.
Eventually, the class might come to understand Marinette's decision. As they struggle to do things on their own, they realize how much effort Marinette had been putting in. This could lead to them changing their ways and maybe even trying to make it up to Marinette if she decides to start helping again.
Well, some might be really amazed. They could see a new side of Deku that they never knew before. His singing might show a different level of confidence or a hidden talent, so they would probably cheer him on.
It could be about how the 78th class in a particular fictional universe reacts to future events. Maybe they face new threats, technological advancements, or social changes. For example, if it's a superhero - themed universe, they might have to deal with more powerful villains in the future. They could also be reacting to changes in their own relationships within the class.
They might be really surprised. Some characters could be flattered by the positive portrayals in the fanfiction, while others might be a bit annoyed if their personalities are misrepresented. For example, Deku might be shy but also happy to see new interpretations of his growth journey.
He would probably be quite amused by some of his past antics. For example, his constant pranks on Iruka-sensei. But at the same time, he'd also see the pain he carried from not having his parents and realize how that influenced his actions. He might react with a bit of regret for some of the stupid things he did out of loneliness, but also be glad that those experiences made him who he is today.
The main characters could also be a combination of students with different abilities or skills. In a world where they need to react to the future, someone with technological know - how, another with physical strength, and a third with great strategic thinking could all play important roles in how the 78th class as a whole responds.
Bakugo would likely be furious. He'd feel betrayed and would probably be the first to attack Deku, yelling at him about how he's thrown away everything they've worked for. Uraraka might be more empathetic. She'd try to understand what drove Deku to become a villain and hope there's a way to bring him back to the side of good.
