Man, I’ve read so many of these. It’s interesting how most writers seem to land in one of two camps: rivals-to-lovers or mutual pining with a side of explosive emotional repression. The first type is all about external conflict—training battles that get too personal, public spats that turn into private conversations. They’ll have Bakugou’s aggression actually chip away at Todoroki’s calm facade, and Shoto’s quiet observations get under Katsuki’s skin in a way nobody else can.
What works, when it works, is when the author remembers Bakugou isn’t just anger. He’s terrifyingly observant. Good fics use that. He notices the tiny flinch when Shoto uses his left side, or the way he holds a cup too tightly. And Todoroki isn’t just passive; his stubbornness matches Bakugou’s, it’s just quieter. Their dynamic develops through these silent recognitions—Bakugou sees Shoto’s fucked-up family trauma and, in his own abrasive way, refuses to coddle him for it. Shoto sees Bakugou’s drive not as mere arrogance but as this single-minded, almost fragile need to prove himself. They meet in this space of understanding that’s built more on actions than dialogue.
A common pitfall is making Shoto too soft or Bakugou too one-dimensionally angry post-canon. The best character development I’ve seen happens when they push each other’s flawed perspectives. Bakugou forces Shoto to engage, to want something for himself beyond his father’s shadow, and Shoto’s unshakeable calm forces Bakugou to confront the parts of himself that aren’t about winning.
