When she later realized her mistake, she confessed to her friend Shen Qingmiao, who manipulated her into staying silent by saying Lan Yuchu would never like her again if he found out. Duan Manyue was too afraid to come clean and instead tried to help and console Lin Qiyue, not realizing that Shen Qingmiao was the one who had schemed against her all along.

In the original story, she waited for Lan Yuchu for three years after Lin Qiyue's death, and they eventually married.
