2024: Julia was exhausted, as if her entire being was on the verge of collapse. In the quiet house where she lived with Carl and her son, every corner seemed to bear witness to the friction that filled their home. Arguments with Carl had become routine, and the love they once shared had evaporated, leaving only resentment and bitterness. Julia tried to conceal the tensions so that her son wouldn't notice, but she could no longer hide the weight of a marriage that had left her empty.

That afternoon, after another heated argument with Carl over something as trivial as housework, Julia retreated to the kitchen, where she immersed herself in the task of washing dishes, trying to clear her mind. Carl was in his usual indifferent mode, hunched over his chair, watching the television without paying attention to her.

The sound of the door to her son's room made her look up. She knew he was watching her. For some time now, her son had begun to notice the cracks in their home, the lack of peace and the constant tension. He was no longer a child, he had grown up and was beginning to understand the dynamics between her and Carl, something that worried Julia deeply. Despite everything, he had always been a good son, concerned about her, and that protective attitude touched her.

The kitchen door slowly opened, and there he was, looking at his mother with that mature expression that seemed to be much more than his age indicated. Without saying a word, he approached Carl, who was absorbed in the television, ignoring what was happening around him. Julia's eyes filled with fear and hope at the same time. She knew what her son was going to do. She had seen it before, when Carl had verbally attacked her or when he humiliated her in front of him. But this time it was different; something had changed in her son.

With the machine ready, he climbed into the capsule that would take him back in time. The trip was not going to be easy, but he had to do it. He had to go back to before his mother and Carl were married. He had to prevent that marriage from ever happening. He travels with a backpack full of evidence of Carl's abuse of Julia.

2005: It was a cloudy afternoon, the cool breeze caressing the fallen leaves in the park where Julia had agreed to meet someone who had sent her a mysterious letter. The envelope, old with stained ink, had arrived that morning with a message that stirred something deep inside her: 'I need you, please come. The fate of all is in your hands.'

Julia sat on the indicated bench in the farthest corner of the park, under a tree that seemed to guard the moment. The clock marked the exact time when a man approached, dressed in clothes that seemed out of place. His demeanor was serious, but his eyes... those eyes felt familiar, and that feeling made her heart beat faster.

When he stopped in front of her, Julia watched him closely, unable to explain why a lump was forming in her throat. Despite her confusion, she remained silent, waiting to see what would happen. Finally, she spoke in a trembling voice."Who are you? Why did you ask me to come?"
