Lady Hyegyŏng argues that Sado's illness grew out of how his father treated him. Yŏngjo housed the infant away from his parents among hostile palace staff. He rebuked Sado in public, and he summoned him only on bad occasions, even washing his ears after speaking to him. The memoir traces a chain from chronic humiliation, to fear of the father, to anxiety and compulsive clothing phobia, to violence. This places the cause in the relationship rather than in innate evil.
First she wrote for her own family's reputation. Later she wrote for her grandson, King Sunjo, after her son Chŏngjo's death exposed her kin to purges. Read this way, each telling is a political act aimed at a particular reader and moment, not a neutral record. Differences between versions show what the teller could safely say when.
Much of the memoir defends Lady Hyegyŏng's natal Hong clan, especially her father Hong Pong-han, against charges that they caused or failed to stop Sado's death. The mechanism: a witness who outlives a catastrophe writes to shift blame onto structural necessity and the victim's illness, protecting her lineage's standing. Her personal grief and her partisan interest are woven into the same narrative.
