In order to survive in the General Mansion, she hid herself just like the heroine, but unlike the heroine's lack of ruthlessness, she was different. Before coming of age, she secretly eliminated her father's concubines, leaving no trace of the illegitimate offspring, all because her mother had a pursuer who was well-versed in medicine and poisons. This man's willingness to support her after her mother's death turned her from a white lotus into a black rose with thorns.
Because she resented her father for failing to protect her mother, this legitimate daughter was ruthless enough to leave only her own bloodline in the General Mansion.
The general fought on the battlefield for most of his life, ending up alone with only a frail daughter left behind, unable to change this regrettable fate.
