The world had changed. Half of all life vanished in an instant, and what remained was silence. The heroes who once protected it now walked like shadows. At Avengers headquarters, Natasha Romanoff was the one who still refused to give up. Every dawn found her in front of the monitors, searching for signals that didn't exist. Steve Rogers usually arrived soon after, silent, steadfast, as if his mere presence was enough to sustain her. "You can't save them all," he told her one morning. "And you can't stop trying," she replied. For a moment, the silence between them spoke louder than any words. ⸻ One day, the headquarters door opened and Scott Lang appeared, disheveled, almost incredulous that he was alive. He brought a theory: the Quantum Realm. Time, he said, didn't flow the same there. Maybe they could use it to go back… and undo the Snap. It was madness, but also the first spark of hope in years. They sought out Tony Stark, the only one capable of making it possible. But he was no longer Iron Man; he lived with Pepper and their daughter, Morgan, in peace. "I've had my second chance," he said, refusing. "I'm not going to risk it." Natasha looked down, disappointed. Steve just murmured, "He'll come back. He always does." And he came back. One night, the genius solved the impossible. He arrived at the headquarters at dawn, carrying a briefcase and a look that mixed fear and faith. "I'm not promising anything," he said, "but I think I found my way back." ⸻ For weeks, the headquarters breathed again. Bruce, Tony, and Scott built the quantum tunnel. Clint was located, Rocket and Nebula returned, and the Avengers were back. At night, Natasha and Steve shared silence in front of the blue reactor. "Did you ever think it would come to this?" she asked. "No," he replied. "But if this works, you'll have a second chance too." "I don't have anyone waiting for me." "Then you'll have me." Their gazes met. And for a moment, the weight of the world seemed to disappear. ⸻ When the tunnel lit up, everyone held their breath. The quantum light illuminated their tired faces, reflecting something they hadn't felt in a long time: hope. It was the beginning of the journey that would change the fate of the universe... and also that of two hearts that, unknowingly, were about to meet in the middle of time.
