On a vibrant spring day, the world outside was bursting with life. Inside the cozy home, everything unfolded as usual. The rich aroma of sautéing vegetables filled the air as Alastor diligently prepared a meal in the kitchen. In contrast, Lucifer sat at his meticulously organized desk, buried under a mountain of paperwork and focused on his tasks. Meanwhile, in her brightly decorated room filled with toys and laughter, Charlie was absorbed in play, her joyful imagination echoing throughout the house.

However, the calm atmosphere was suddenly disrupted by the insistent chime of the doorbell, slicing through the tranquility. Lucifer paused, pushing his chair back as he stood with a furrowed brow. He exchanged quick glances with Alastor, who had also put down his cooking utensils, and with Charlie, who eagerly bounded from her room. They all moved toward the front door, their curiosity piqued.

When Lucifer opened the door, a warm grin spread across his face, brightening his features. There stood Rem, vibrant and cheerful, with a couple of colorful bags in tow, sunlight dancing in her hair.

Lucifer's voice rang out with joy, “Sister! How I've missed you!”

Charlie jumped up and down, her eyes sparkling with delight. “Auntie! You're back!”

Amidst the joyful reunion, Alastor lingered just a step behind, subtly studying the newcomer with a mix of intrigue and contemplation. His usual grin was slightly more reserved as he took in the scene before him.
