A girl stands at the edge of the sea and feels it calling to her. The sea speaks like a tempting friend, promising a place where nobody can hurt her, break her heart, or tear her hopes apart. The poem treats this pull seriously: she finds it tempting, and the thought of ending her life feels like a kind of calm.
What changes things is a memory of a boy with striking blue eyes and a black fringe. The details are small and tender, which suggests how much he matters to her. In the last stanza she decides to live, and the reason is notable: not for herself, at least not yet, but for him.
The mood moves from quiet and haunting to fragile hope. The sea's voice is soothing rather than frightening, which makes the danger feel real. The ending is not a neat cure, but it shows how one person's love can be enough to hold someone back from the edge.
