Qu Muhua is Lu Xicheng's mother, who recently underwent breast cancer surgery. She initially appears accepting of Shi Wan's marriage to Lu Xicheng but then stages a self-inflicted stabbing, using Shi Wan's hand to hold the knife against her own abdomen. She accuses Shi Wan of murder, delivers dying words blaming her for the family's ruin, and urges Lu Xicheng to take responsibility for Lin Zaixin before collapsing.
