She guards the lighthouse, waiting for someone who will never reach the shore; she records the storm, but cannot predict the hurricane in her heart. When marine biologist Li Lan and meteorological observer Ye Tan met on the eve of the storm, one of them was carrying the secret of her mother's ALS, and the other was hiding the poems and lies of their youth. Within three days, tides, toxins and unsent love letters intertwined into an irreversible redemption. In the end, the moonlight sank to the bottom of the sea, and their story became the gentlest legend in the sea breeze.
Concept: Love is an addiction that is done knowing that it cannot be done, a tide of destruction and redemption that goes hand in hand.
