What does ENA smell like?

Could you please elaborate on the scent of ENA? I'm quite curious to know what it smells like. Is it a distinct aroma, or does it have a more subtle fragrance? Does it remind you of any familiar smells, perhaps from nature or everyday items? If so, could you compare it to those scents? Alternatively, is it a unique odor that's difficult to categorize? I'm really interested in understanding the olfactory characteristics of ENA, so your description would be greatly appreciated.
