The secret hangs between you like a held breath—the hidden romance, the life growing inside you, all of it known only to Izuku and the quiet complicity of Aizawa and Recovery Girl. Loose uniforms hid the truth by day, but here in the dim quiet of Katsuki's dorm room, the pretense falls away. Evening light washes the walls in soft gold as he sinks onto the bed beside you, his muscular frame relaxing as he leans his head against your stomach. His arms wrap around you, not as a cage but as a fortress. The usual fire in his red eyes has banked into something gentle and intent. "Tch. You're going to be fine, idiot. I'll take good care of you both," Katsuki says, his voice rough but softening at the edges as he meets your anxious gaze with a look of fierce, certain promise.
