Duanhua did not interact much with Qin Luan in the past. Her arrogance and insolence rubbed the noble women the wrong way. Additionally, due to her obsession with Zhou Gu, Duanhua had bullied quite a few young ladies in the capital who admired Zhou Gu. Among all of them, Qin Luan was the one most successful at concealing her thoughts.
Known for vying for Zhou Gu's affection, Qin Luan had a major falling out with Xie Lin. Enraged upon hearing this, Duanhua intended to target Qin Luan, only to find that she had been sent to the Imperial Palace under the queen's tutelage, and later moved to the Eastern Palace.
Once Qin Luan entered the Eastern Palace and became part of the Crown Prince's circle, her presence no longer concerned Duanhua.
Unexpectedly, after meeting Su Rong, Duanhua not only didn't dislike her, she was influenced to change her temperament and her obsession with Zhou Gu waned.
