Qin Song struggles against the raging current, trying to protect that one tender glimmer. But the great river of Tang history surges on, and how small an individual's strength is against it. Their love is like a candle flickering in the wind, on the verge of being snuffed out by history's raging storms. In the end, only a faint lingering fragrance remains, haunting the depths of time and telling of endless regret and the ravages of the years.
