What are the scary details in War and Beauty?

There are two handkerchiefs in the play, one is a lotus and the other is a water lily. The flowers of these two handkerchiefs are similar in appearance, but they are not of the same kind. The water lily on the left is a metaphor for Qian 'an, and the flower language is enchanting, which conforms to the transformation of Princess Qian 'an. The lotus on the right is like a princess, a silent love, and the love between Kong Wu and the moon. I feel that the screenwriter has arranged the ending very early.
