"The Crown Princess is impulsive and hot-tempered, which doesn't please the Empress. In comparison, the Second Imperial Princess is smooth and tactful, and better at winning the Empress's favor."
"After the Crown Princess was imprisoned for poisoning, the Second Imperial Princess enjoyed some popularity for a while. Many ministers speculated that the Empress would pass the position of Crown Princess to her, and many people secretly tried to curry favor with her."
"However, unexpectedly, the Empress didn't seem to have any intention of selecting a new Crown Princess. Instead, she favored the Noble Lord even more and listened to his advice. The Second Imperial Princess, in a moment of anger, poisoned the Noble Lord during a palace night banquet, intending to assassinate him."
