Katsuki Bakugo (enemies)

At UA, everyone knew that Katsuki Bakugo and Hurdonkey couldn't be together for more than five minutes without arguing. "Shut up, you fourth-rate firecracker!" Hurdonkey yelled. "Who are you calling a fourth-rate firecracker, idiot?!" Bakugo retorted. Their classmates were used to seeing them fight over anything and everything. They were sworn enemies. But outside of school, Hurdonkey had something very important: her older brother, Ivan. Ivan loved her very much. He always protected and spoiled her. "You're my little princess," he would say, ruffling her hair. "I'm not a little girl anymore," she would protest. "To me, you always will be." One morning, Ivan arrived excited. "Hurdonkey, today I want to introduce you to my best friend." "Your best friend?" she asked. "Yes. He's a great person. I'm sure you'll like him." Hurdonkey nodded, though she didn't seem very interested. "Okay." He spent all afternoon thinking about who it could be. Maybe someone nice. Maybe someone funny. When the time came, she heard the front door open. “I’m home!” Ivan yelled from the doorway. Hurdonkey came out of her room to greet him. “Hey, Ivan. Hey, Iva’s friend…” The words died in her throat. She froze completely. Standing before her was Katsuki Bakugo. Bakugo froze too. “YOU?” they both shouted at the same time. Ivan looked at them, confused. “You know each other?” “Yeah!” Hurdonkey replied. “Too much!” Bakugo growled. “He’s the most insufferable person I’ve ever met.” “You’re talking about yourself!” “Shut up!” “Make me!” Ivan watched the scene, wide-eyed. “Wait… are you two enemies?” “YES!” they both yelled again at the same time. Hurdonkey’s brother sighed. “I can’t believe my best friend and my little sister hate each other.” "I can't believe YOUR best friend is this arrogant jerk either," Hurdonkey said, pointing at Bakugo. "And I can't believe YOUR sister is so annoying," he retorted. Ivan put a hand to his face. "This is going to be a disaster..."
