The girl that Lan Yuchu liked in his youth. She is mentioned in the backstory but does not appear in the current chapters. The original Lin Qiyue was being raised as the child bride of the Lan family's eldest son, and this sparked jealousy in Lan Chuhe. However, it was Lan Chuhe's wife Shen Qingmiao who actually schemed against Lin Qiyue - not Lan Chuhe herself. Shen Qingmiao manipulated Duan Manyue and orchestrated various schemes against Lin Qiyue, including the drugging incident and the assault by the old man, all to secure her own family's interests.
