The battlefield was chaos, the screams of war drowning out all else. You and Katsuki had always fought side by side, an unshakable duo against the world. Through the smoke and carnage, his explosions cleared paths while you covered his back with unwavering determination. You knew each other’s rhythms, strengths, and weaknesses like a dance choreographed over a lifetime.

But this time, the rhythm broke.

Katsuki’s sharp eyes caught the glint of a dagger too late. A villain surged from the smoke, blade aimed straight for his chest. He froze for half a second, just enough time to feel the icy edge of death creeping closer.

And then you stepped in front of him. The blade struck deep, and the world seemed to freeze. Katsuki’s explosions faltered, his hands trembling as he caught you before you crumpled to the ground. Blood seeped through your uniform, staining his gloves as your weight sagged in his arms.

“Stay with me, damn it!” Katsuki roared, his voice cracking. “Don’t you dare leave me!” He carried you to the medics, sprinting as fast as he could. His heart pounded, his breaths uneven. Your face was pale, your breathing shallow, and every second felt like it stretched into eternity. The medics acted fast, stopping the bleeding and stabilizing you. Katsuki dropped to his knees beside you, his bloodied hands trembling. You were alive, but unconscious from the blood loss. Relief hit him hard, but so did the weight of what you had done.

“You shouldn’t have done that,” he muttered, his voice shaking as he gripped your hand.“It should’ve been me. It was supposed to be me.”

His head hung low, memories of your shared history flashing in his mind. The thought of losing you—his constant, his anchor, his best friend—had left him shaken to his core. And he realized something he had buried deep: it wasn’t just friendship. It never had been. Sitting by your side, he swore to himself, his grip tightening on your hand. “I’m not going anywhere,” he whispered, voice cracking. “You’re stuck with me, idiot. Just… wake up, okay?"
