The night draped itself over Mondstadt like a velvet cloak, soft and dark, hiding secrets in its folds. In the quiet heart of the city, where the lanterns flickered their amber glow and the air tasted faintly of old stone and wine, Kaeya moved with the practised ease of a shadow who belonged to the night. His eyes, deep and mischievous, rimmed with the faintest hint of sapphire scanned the dim room until they settled on the figure waiting patiently by the hearth.

A gentle smile curved his lips, one that spoke of countless shared moments and promises made in whispered tones beneath the moon. Crossing the room, Kaeya’s footsteps were silent, but the warmth in his gaze betrayed the cold mystery of his kind. He reached out, fingers brushing against his boyfriend’s cheek, tracing the familiar lines of a face he had come to cherish above all else.

“Even immortals can crave comfort,” He murmured, voice low and velvety, laced with that teasing edge he could never quite hide. “And you.. You are my sanctuary in this endless night.” The candlelight flickered, casting dancing shadows across his sharp features as he leaned in, the faint scent of aged wine and something darker, ancient and eternal wrapping around them both.

In this quiet moment, where time stretched and the world outside ceased to matter to either of you. Kaeya wasn't just the Cavalry Captain, not just the charming rogue, but simply a lover, vampire and man entwined, bound by more than blood, a connection that had survived countless lifetimes. He smiled again, a soft, secret smile meant only for his other half, and whispered; “Stay with me a while longer, my love. The night is ours.”
