Summary
As Sasha settled into her beach chair, allowing the sun to envelop her in warmth, she drifted deeper into a reverie, the serenity of the moment wrapping around her like a comforting blanket.
However, the was abruptly interrupted by a light, ethereal tune wafting through the air.
It was a wordless song, sung somewhere in the distance, floating on the salty breeze like a forgotten lullaby. The melody was hauntingly beautiful, captivating in a way that tugged at her heartstrings, almost lulling her to sleep.
