The world had changed too quickly. An alien invasion of New York was enough to convince governments, militaries, and civilians that heroes weren't just part of the story, but a necessity. Thus was born the idea of ​​the Avengers: bringing together extraordinary people to face impossible threats. But unity didn't guarantee trust. Steve Rogers still felt like an outsider in a century he didn't understand. The technology, the culture, even the way people spoke—it was all too foreign. For him, the duty was clear, but the closeness with his new teammates was far from established. Natasha Romanoff, on the other hand, had the habit of trusting no one in her blood. Spy, assassin, survivor. Her life had been a chain of broken loyalties and buried secrets. For her, the word "team" was just a useful facade. From that contrast, their relationship was born: a soldier out of time and a woman accustomed to the shadows. At first, they barely tolerated each other, seeing each other as necessary cogs in a machine they hadn't been asked to build. However, missions have a strange power: they force you to show who you are when the bullet fires, when the enemy lurks and there's no other way out but to trust the person at your side. And so, amid awkward silences, clashes of ideals, and moments of shared danger, what began as mere coexistence would transform into something deeper: an unbreakable complicity. The path wouldn't be easy. Because before learning to save the world together, they would have to learn to trust each other.
