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.
Deku could also become more withdrawn. He might start to overthink his interactions with Bakugou. He'll wonder if he did something wrong to provoke the accident, even if it was truly an accident. This self - blame could make him pull away from Bakugou and their shared activities, like training together or being in the same group projects at school.
The accident could also have an impact on the overall dynamic of their friend group. Their friends might take sides, some feeling more sympathetic towards Deku and being angry at Bakugou, while others might understand it was an accident and try to mediate. This could create tension and interesting plot developments in the fanfiction.
Some characters might try to understand Deku's motives. Kirishima, who was close to Bakugou, would be angry at first but might also try to find out if there were any extenuating circumstances. However, many would be afraid of Deku, seeing him as a threat now that he has killed one of their own.
The theme of growth is also very common. Both characters experience growth in different ways. Bakugou grows in terms of his emotional intelligence and how he treats others, especially Deku. Deku grows in his ability to stand up for himself and not let Bakugou's words and actions break him. And there's often a theme of communication too. How their lack of proper communication has led to the situation and how better communication can solve their issues.
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.
One popular 'bakugou hurts deku fanfiction' is 'The Pain Between Us'. It delves deep into the complex relationship between Bakugou and Deku, exploring how Bakugou's actions can sometimes cause emotional harm to Deku. Another is 'Scars of Words' which shows how words from Bakugou can cut deep into Deku's self - esteem.
One possible motive could be a long - held grudge that has festered over time. Maybe Bakugou's constant bullying in their past finally pushed Deku over the edge. Another could be some sort of mind - control or dark influence that made Deku act out of character.
The relationship could start with hatred. Bakugou may initially be enraged that Deku has become a villain. But as time passes, he starts to see the reasons behind Deku's transformation, which could lead to a more complex relationship.
Bakugou could use his words. He might tell Deku that he believes in him. For example, he could say 'Deku, you may be a nerd but you're a strong nerd.' It's a backhanded compliment but it shows he has faith in Deku.
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.
Well, I'm not sure about a specific 'deku x bakugou dies fanfiction' that is the best. However, many fanfiction writers might explore this concept in different ways. Some might focus on the emotional aftermath for the other characters, while others could create alternate universes where this event leads to a whole new set of adventures or challenges for the remaining characters in the My Hero Academia universe.
