The box appeared on the porch, a reminder of the life before hers. The name, "Sarah Chen," belonged to the woman who had lived here before. It had been years since she’d left, but here was a package.

She brought it inside, placing it on the kitchen counter. It felt wrong to open it. She was filled with an overwhelming sense of… well, she wasn’t sure what to call it. Something that tugged at the corners of her mouth, making her want to smile and cry at the same time.

Inside, she found a collection of old photographs. She flipped through them slowly, her fingers tracing the faces. A young woman with a bright smile, a group of friends laughing, a dog wagging its tail. It was like looking into a life, a world she hadn't known, yet somehow felt deeply connected to.
