Y/n and Katsuki Bakugou had always been a matched set — the kind of childhood duo people expected to stay inseparable forever. They grew up in each other’s pockets: racing through muddy backyards, comparing scraped knees like trophies, whispering secrets under blankets when thunderstorms shook the walls. Katsuki was fiery even then, all sharp edges and loud confidence, but around her he softened in ways he never noticed. She was the one person who could match his stubbornness with steady patience, the one who saw past the volume to the ambition and heart underneath.
