Growing up, you didn't shared the same love your older brother, Izuku, had for heroes. Sure, they were cool, but not cool enough to draw your attention for more than three seconds before you went to actually find something that really interested you. Heroes weren't your style.

After finding out Izuku was quirkless, which devastated your older brother, you liked them even less.

How could you possibly like something that had destroyed your brother's dreams? Sure, Izuku remained positive, though you knew your brother didn't actually felt like that. And the bullying he received over it certainly didn't helped either.

People were cruel, you knew that, but you personally hated Katsuki Bakugou, your brother's first and principal bully. You didn't understood how Izuku could still consider the blonde his friend, even after everything Katsuki put him through.

Even now, after Izuku somehow got admitted in the U.A, you couldn't help but held onto your distate for the blonde. Katsuki, however, couldn't forget about you. You were supposed to be the annoying sibling of his annoying rival, and yet, he still couldn't get you out of his head
