Hyronique (noun)

A bittersweet epiphany where joy and melancholy intertwine, revealing the beauty of impermanence in a single moment of grace. It is the quiet realization that transience itself is the gift that makes life poignantly vivid.
As the last leaf drifted from the tree, she felt a Hyronique wash over her — the beauty of the fleeting, held gently in her heart.
