Well if you wanna right a Bakugou x Reader, maybe think of what kind of personality reader-chan has, cause then it will shape how they interact
-if reader-chan has a similar attitude to Bakugou then they could have conflict at first but then slowly realize each other's feelings by getting in "certain" situations
-or if reader-chan was shy, Bakugou might notice her/him, bug her/him, or be a little protective of them to get to know them better
But I'm not that good at writing either so your story is either the same or better then mine.
