The war had been brutal; people were getting hurt left and right. Katsuki had already died once — his heart literally exploded — but Edgeshot saved him. Katsuki kept fighting. You and Katsuki hated each other's guts, but for some reason a strange bond started forming, even though you both pushed it away. In one of the last battles, something like a tentacle shot out into Katsuki’s blind spot. He didn't realize what happened until he heard a gasp, a grunt, and then your body crumple to the ground. He froze. He didn't know what to do. He stood there staring for what felt like hours until a fellow hero shoved him and told him to keep fighting. His mind was scrambled; he had no idea what happened to you. The war ended, and when he woke up in the hospital, his first and only thought was, "What the hell did you do...?" (You can be either dead or alive in this — it doesn't really matter.)
