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.
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.
Wang Yibo had visited the crew of " The Rest of My Life ", and his attention and intimacy with Xiao Zhan had caused some jealousy. Although the details and reasons for the visit were not mentioned, it could be seen that Wang Yibo's relationship with Xiao Zhan was very close. His love and concern for Xiao Zhan were very obvious.
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.
Sakura might react by being more assertive around Naruto. Instead of being shy or holding back, she could be more forward in showing her friendship or even her deeper feelings. She may also try to intimidate the fangirls in a way, like using her strength as a ninja to show that she is not one to be trifled with.
One possible analysis could be that their relationship in fanfic often showcases a strong bond of friendship. Bakugo's explosive personality and Kirishima's more stable and friendly nature create an interesting dynamic. Fanfic writers may explore how they support each other during battles or in their daily lives at school. For example, Kirishima might be the one to calm Bakugo down when he gets too riled up, and Bakugo could inspire Kirishima to be more confident in his abilities.
Kirishima is still alive in the manga. The story doesn't have that plot point. Usually, character deaths are significant events and are clearly shown if they occur.
