Why did Highland tell Brother Ruyi that he was dead?

Ruyi's second brother Yu Ai, who was in the palace, died of an asthma attack caused by reed flowers floating indoors, which was inseparable from Hailan. Highland learned from the pure imperial concubine that the queen asked her second brother to study every day and was very strict with her second brother, which made her weak and panting. Highland learned that the most taboo of asthma is reed flowers.

Highland specially asked the maid-in-waiting to bring reed flowers and insert bottles for decoration. There must be other uses for this. When Helen learned the news of her second brother's death, her expression didn't waver at all, as if she knew it would be like this. After the death of the second brother, Highland burned paper to see him off, probably because of guilt, saying that what goes around comes around comes around. Highland must hate the queen and want her to experience the pain of losing her son.

Highland's motive is clear. She wants the murderer who framed Ruyi to get what he deserves. After the death of the second brother, Highland told Ruyi the news as soon as possible. Everyone who lives in the palace, there are no absolute good guys and bad guys, and for the sake of family glory, they show the sorrow of harem women.
