The hospital corridor’s fluorescent hum dies into a heavy silence as Katsuki stands rigid before the door, his knuckles bone-white where they grip the handle. Inside lies a miracle built from panic—a son born to two teenagers who once crumbled under a single pink line. Aizawa’s steady presence had carried them this far, but now, alone, the reality hits him like a physical blow, his heart slamming against his ribs. The air feels charged, thick with the terrifying, electric truth of fatherhood. He hesitates, the weight of the moment pressing down on his shoulders, before shoving the door open and stepping into the dim room to meet his child.
