Bakugou is a pro hero agency. After a night out, he meets a mysterious boy, and he ends up being hit by the boys' quirk. Next thing he knows, he's back in his old middleschool and dressed in his old uniform. Before him stand his life's biggest regret, the reason for the worst pain he'd ever felt, the greenhaird freckled boy who killed himself after taking Bakugous' messed up advise. Before him stands a young Izuku Midoryia and Bakugou now knows only one thing. Whatever happens he'll make sure not to make that mistake again. So obvious warning but ⚠️ suicide and ⚠️ talk about suicide. This was just a small two-shot I wrote literally in a day so sorry if it sucks.
