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.
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.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
He might cry a lot. Deku is very emotional, and being cheated on would be a very painful experience for him. He could also get angry, which is rare for him, but this situation would be so unjust that he might not be able to hold it in. He'd probably start to question his self - worth too, thinking that there was something wrong with him that made his partner cheat.
In deku harem fanfic, a common characteristic is the expansion of Deku's relationships. It may include his female or male counterparts depending on the nature of the fanfic. The stories usually involve how Deku's heroic deeds and kind heart attract others to him. There is often a build - up of emotional bonds between Deku and the members of his harem. The fanfics might also play with the idea of how Deku balances his relationships while still focusing on his goal of becoming a great hero. This can lead to some interesting plot twists and character developments within the story.
Deku might be initially shocked. He's used to Bakugou's aggression, but an actual injury is different. He could be in pain and disbelief at first. Then, he might try to downplay it, especially if he doesn't want to cause trouble for Bakugou, because Deku is generally a very forgiving character.
Well, 'Deku's Harem of Heroes' is a notable one. In this fanfiction, Deku finds himself in a harem situation with his fellow hero classmates. The story might include elements like how they support each other not only in their heroics but also in their personal relationships. It could also explore how the other characters in the harem interact with each other, and how Deku's presence affects the group dynamics as a whole.
One common theme is the development of relationships. Since it's a harem concept, it focuses on how Deku forms connections with multiple characters. Another theme is often growth, not just for Deku as a character but also for the members of his harem. They all grow together in different ways.
I think Uraraka would be very excited. She has always been a big supporter of Deku. Meeting Future Deku would give her a chance to see how far he has come, and she might also get some inspiration for her own hero journey. Plus, she's a friendly and emotional character, so she'd likely be thrilled at the opportunity.
