Possible perfume notes:
Fleeting Sweetness: draws you in and promises more than it can deliver.
Sour smoke: a faint memory of something that did not go as planned.
Metallic, ink, ozone: a hint of failed technology, brokenness.
Musk, leather: a musty stale odor, reminiscent of missed opportunities or bad choices.
Salt, brine: tears, the sad sting of regret.
And a mildly pungent lingering smell of shame and embarrassment.
