One popular type might be the friendship - centric ones. These fanfics explore the complex relationships between Todoroki, Deku, and Bakugou. They often show how their different personalities interact and how they grow to understand and support each other. For example, a fanfic could focus on their training sessions together, where they learn from each other's strengths and weaknesses.
There's also 'Unexpected Affection'. In this fanfiction, the kiss between Deku and Todoroki occurs in a very tense and emotional situation, like after a big battle where they realize their true feelings for each other. The author does a great job of building up the anticipation before the kiss.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfics for various fandoms, including those related to Todoroki, Deku, and Bakugou. The search function on AO3 allows you to easily filter for the specific relationship you're interested in.
Another way is to join fan communities dedicated to the series they are from, like My Hero Academia forums. There, fans often share and recommend their favorite fanfictions, including those with Deku and Todoroki kisses. You can also ask for specific recommendations in these communities.
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.
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.
Todoroki can start by simply being there for Deku. Just sitting with him in silence when Deku doesn't feel like talking. It shows that he's not alone. Also, Todoroki can share his own struggles. Since he has his own complex family situation, he can relate to feeling down sometimes. This can make Deku feel that his problems are not unique and that it's okay to not be okay.
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.
One common theme is friendship development. Given their different personalities, seeing how they grow to become friends or at least respect each other more is a popular plot. For example, they might start off as rivals in a hero training exercise and end up having each other's backs.
