The rain fell in sheets, pounding the cobblestone streets of old Prague. Amelia ducked under an awning, shaking droplets from her auburn hair. As she peered out at the glistening city, a figure caught her eye - a tall man in a vintage coat, seemingly unbothered by the downpour.

Their eyes met, and time seemed to slow. The stranger approached, a crooked smile on his face. "Terrible weather we're having," he said in accented English.

"I don't mind it," Amelia replied, entranced by his piercing green eyes. "I'm Amelia."

"Viktor," he said, taking her hand. "Perhaps you'd join me for coffee? I know a charming café just around the corner."

Amelia hesitated only a moment before nodding. There was something magnetic about Viktor, something that made her want to follow him anywhere.

The café was cozy and warm, filled with the aroma of fresh pastries. As they sipped rich espresso, Amelia found herself captivated by Viktor's tales of old Prague. He spoke of the city as if he'd lived there for centuries, describing long-forgotten legends and secret passages with vivid detail.

"You make it sound like magic," Amelia laughed.

Viktor's eyes twinkled. "Perhaps it is. Prague has many secrets, after all."

As the rain tapered off, they wandered the winding streets. Viktor showed her hidden courtyards and whispered stories of alchemists and astronomers who once walked these very paths. With each step, Amelia felt herself falling deeper under the spell of both the city and the mysterious man beside her.

Days passed in a whirlwind of laughter and discovery. They explored ancient libraries, danced in moonlit squares, and shared stolen kisses atop the astronomical clock tower. Amelia had never felt so alive, so connected to another person.

But as their time together stretched on, she began to notice odd inconsistencies. Viktor's knowledge of history seemed too personal, too real. Sometimes, when she looked at him in just the right light, he appeared to shimmer at the edges, as if not quite solid.

One evening, as they stood on the Charles Bridge watching the sunset, Amelia finally voiced her suspicions. "Viktor, who are you really?"

He turned to her, his eyes filled with an ancient sadness. "I am exactly who I appear to be, my dear. But I fear I haven't been entirely truthful about when I am from."

Viktor explained that he was a time traveler, cursed to wander through the centuries, never able to stay in one place for long. He had fallen in love with Amelia, but knew their time together was limited.

Tears welled in Amelia's eyes. "How long do we have?"

"Until midnight," Viktor whispered, pulling her close. "Then I must go."

They spent their final hours in a frenzy of passion and desperation, trying to memorize every touch, every whispered endearment. As the clock struck twelve, Viktor began to fade.

"I will find you again," he promised, his voice echoing as he disappeared. "In another time, another place. Our love will transcend the centuries."

Amelia stood alone on the bridge, her heart aching. But as she gazed out at the twinkling lights of Prague, she felt a spark of hope. Somewhere, somewhen, they would meet again. And until then, she had the magic of their impossible romance to keep her warm.
