I'm not sure specifically what the 'oi and oy secret story' is. It could be something very personal or a made - up story within a particular group. Without more context, it's hard to tell.
Bakugou might be initially shocked. He's used to Izuku calling him 'kacchan' for so long that it's become a normal part of their relationship. So, when Izuku stops, it could throw him off balance.
No. It is not appropriate. Fanfic should be a form of creative expression that adheres to ethical and moral standards. Sexual fanfic, especially when related to a character like Bakugou, goes against the respect that should be given to the source material and the character.
Fanfic related to 'bakugou' often involves writing fictional stories about the character Bakugou from certain anime or manga. However, 'sex fanfic' involves inappropriate and unethical content which is not acceptable in many communities. We should focus on positive, non - sexual fan - created content like adventure or friendship stories centered around Bakugou.
Definitely not. Bakugou is still alive and kicking in the manga. The creators have kept him around to drive the story forward and engage the readers with his dynamic personality and actions.
His aggression might become more unhinged. Without the moral compass of the hero side, he could be more willing to use excessive force. He'd still be competitive, but now it would be against heroes instead of his fellow hero trainees.
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.
