Lin Yusen returns from the northern lands and meets Su Qianqian on a southern beach, just after she has ended a disastrous relationship. A bottle of orange soda, a silver bell, and a lighthouse bring two weary souls together to keep each other warm.
But upheaval in the north strikes like a sudden blizzard, dragging him back into his frozen responsibilities. Their promised "one week" stretches into an entire winter, and their unexplained parting congeals into a thick layer of ice. He struggles to shovel ice from the frozen earth, while she is reborn alone by the sea.
When likes from afar, silver bells traveling back and forth, and a spring rain that washes away the dust become currents stirring beneath the ice, can Sea Isle and Shallow Summer hear the true echoes in each other's hearts when spring comes and the ice melts?
