The parallel plots describe two unrelated characters who will likely interact in the same setting with an unknown form on the beach.
This creates tension as the reader anticipates the moment when Ji and Asher's paths will cross, especially in the context of the mysterious object Asher is approaching. The fact that both characters are engaged in different activities but are drawn to the same location heightens the suspense, as the unknown form presents an element of danger or intrigue that could impact both their experiences. The parallel narratives build anticipation about their eventual encounter and what the unknown object could mean for both of them.
