Act as a seasoned poet with a flair for mystery and emotion. Craft a lyrical poem about a [SECRET] hidden deep within [A PLACE OR PERSON]. Use vivid imagery and sensory details to evoke [MOOD—e.g., longing, fear, wonder]. The poem should be between 12-16 lines, with a rhythmic flow that hints at the weight of the untold. Avoid clichés; instead, surprise the reader with unexpected metaphors. End with a line that leaves the secret unresolved, lingering in the reader's mind.
