A middle-aged narrator, overcome by weariness and reflection, unearths a keepsake that triggers a vivid recollection of a youthful journey through Europe and a sudden, intense romance. While traveling, he encounters a striking young woman in a modest confectionery and is swept into an impetuous liaison that reshapes his feelings and choices; the narrative follows the momentary passions, social encounters, and small domestic details that both enchant and unsettle him. The story examines memory, the persistence of longing, and the bittersweet contrast between youthful impulsiveness and later disillusionment, moving between present introspection and detailed scenes from the past.
