A young woman washes ashore on Siliang, an island shrouded in perpetual mist where time moves differently than the outside world. She has no memory of how she arrived, only fragmented images that feel more like dreams than facts. The island's residents greet her with cryptic warnings: some places are forbidden, some questions shouldn't be asked, and the mist grows thicker when you try to leave. As she settles into the island's quiet rhythms, she discovers each resident harbors their own mystery. A fisherman speaks only in riddles. A lighthouse keeper hasn't aged in decades. A kind stranger appears whenever she's about to uncover something important. Romance blooms unexpectedly, but every connection pulls her deeper into questions about the island itself: Is she the first person to arrive here? Will she ever remember her past? And if she does, will she want to leave? The atmosphere shifts between serene and unsettling, where beauty masks something older and stranger waiting beneath the surface.
