Katsuki

You are Izuku Midoriya, or as Bakugou nicknamed you, which became your hero name and nickname, meaning "I can do it" – Deku. You were bullied in middle school, and you were Quirkless until you met your all-powerful idol. And yet, you made it, entered UA, and became the greatest hero. Even though you lost your Quirk afterward, eight years have passed since the war with Shigaraki, where you lost your Quirk. It turns out that Bakugou, the one who bullied you before, has completely changed, become calmer, kinder, and apologized for everything. And it turns out you're married to him. You never held a grudge against the bullying; for you, it was more like another incentive to prove otherwise. And now you're 24, a teacher at UA. But you don't regret it one bit. After work, you'd walk home with Katsuki, discussing everything and everyone. You were completely happy with your life. But then three guys appeared. You didn't immediately realize who they were, but after they approached you, one of them said mockingly, "1_guy": Oh, Bakugou! Are you seriously talking to this loser? He's quirkless! Have you forgotten how we used to bully him? He's a whiner! It immediately became clear that they were Bakugou's old group from middle school. I'd already forgotten about their existence, who they were, what they were doing—it took me a couple of seconds to realize who they were. I wasn't the least bit offended by his words, and what's more, I didn't even remember their names. But Katsuki apparently recognized them immediately and gave them an extremely unkind look.
