Mom's panicked warning opens the episode: she urges young Nina to run, claiming Nina's father and grandmother want her dead. Nina, terrified, demands why her dad framed Grandpa and killed everyone in the Chancellor's Mansion. The father appears, ordering obedience—he'll spare Nina if she complies, or kill her and her mother if she doesn't. Nina pleads about her tenth birthday and accuses him of killing his wife for a concubine. Overwhelmed, someone offers their blood and vows revenge in another life, shouting "I'm reborn!" The episode ends on that blood oath and Nina's uncertain fate.
After finishing 5,000 world tasks, the Host receives a Rebirth Elixir and the system warns it will disengage once she returns to life. Reborn as Miss Grant, she steps back into the Grant household determined to change past events. She confronts family truth: Warren married her mother for status, later accused Mom of coming between him and Flora, and Mom never expected he'd kill her. Miss Grant prioritizes taking her mother away from the Grants. At Mrs. Grant Sr.'s door she meets Sylvia's polite smile; Nina refuses, 'not interested,' leaving their rivalry unresolved and the plan at risk.
At lunch, Nina skips a visit to Grandma and hears that an imperial chef has been sent to her maternal grandmother. Family members trade barbs about status—Uncle Reed controls the canals, her father is only a fourth-rank official, while a woman boasts 'I'm the Chancellor's granddaughter' and promises to use that advantage to rise and crush the Chancellor. The household erupts with sharp commands and an insistence to go see Grandma. Nina appears at the house, confronts her presence, then the episode ends with her calling 'Mom' repeatedly, the cause and consequence left unresolved.
Nina refuses to visit her grandmother after another slight and insists she'll stay with her mother. Mom tries to persuade her but reveals Nina's father forbids them from going to the Chancellor's Mansion, so a visit would anger him. At the mansion, Mrs. Grant Sr. summons Mrs. Grant and Miss Grant; Faye's closeness to Grandma is exposed—she spreads lies, wears designer clothes, and is favored while Sonia is humiliated. Desserts from Grandma are steered to Faye, deepening the household split. The episode ends with Mom forced to choose whether to defy Dad and confront Grandma or keep Nina away.
Nina arrives with her mother Sylvia at Mrs. Grant Sr.'s to confront relatives who have long rejected her. Nina admits she pretended to be stupid but now knows they'll never accept her and refuses to beg: "Do you expect me to beg you on my knees?" Sylvia apologizes for failing to protect Nina and keeps crying, while relatives accuse her of using tears to get family keeps—hairpin, brush, fabric—leaving her "nothing left." Nina vows to expose their true colors. They stand before Grandma and the family; the confrontation is set and its outcome remains unresolved.
Grandma accuses Sylvia of stealing a treasured brush and fabric; Nina defends Sylvia and tries to calm the courtyard dispute. The argument intensifies as Grandma accuses Nina of lying and warns about reputation, while Miss Grant tells Sonia to keep Mom quiet during the confrontation. Nina then apologizes and Sylvia insists she never took anything. When Grandma finds her belongings in Sylvia's courtyard, she suddenly calls it protection and orders Paula to move her things back and to remove any valuables from Sylvia's courtyard. Sylvia is left vulnerable as the household prepares to carry out Grandma's seizure.
At the General's Mansion Miss Grant demands her belongings back from Sylvia, arguing her sister shouldn’t be forced to mind them. Servant Paula is ordered to collect every item, but the household resists and Miss Grant finds even maids ignoring her. Faye summons Warren, then forces a transfer of the household token so someone new can assert control, declaring, “From today on, I’m in charge.” Mom praises Grandma as the better option, while others warn, “People would laugh at Dad” if an illiterate elder ran the house. Authority has shifted, but the evacuation of Miss Grant’s control and the family split remain unresolved.
At a tense family meeting, Nina insults Mrs. Grant Sr. by saying she’s from the countryside and “can’t even write her own name,” sparking class-based arguments. Dad angrily confronts Warren for upsetting Mom and warns him to stop pressuring the elderly woman. The fight escalates when Dad praises Flora — revealed as a maid from the countryside — and suggests she manage the household because she cheers Mom up. Nina repeats that Dad told Mom to learn from Flora, calling her “lowly.” The family fractures over who should run the house, leaving control unresolved.
At a visit to the Chancellor's mansion, Melanie derides Flora as a concubine and a maid, provoking a confrontation that leaves Nina's mother publicly humiliated and slapped by her husband. Nina and her family learn the father has handed house management to Flora and fears the insult becoming a scandal—"The Emperor takes legitimacy seriously." Grandma urges a deeper fix while Nina offers to apologize to Melanie to contain the fallout. The household scrambles between concealment and consequence, and the episode closes with a family member bluntly urging: "You should just divorce her, Dad."
During a family confrontation at the Grant household, young Nina lashes out, accusing relatives and demanding accountability after months of bruises and whispered rumors. Her sisters press Dad for a decision, but he calmly defends bringing Flora into the household, arguing a concubine safeguards an heir. Nina then accuses Grandma of killing her brother and collapses into an emotional attack that provokes the other women. The argument spins toward physical punishment until Uncle Reed and Uncle Evan arrive and stop the assault. Their timely entrance averts violence, but the father’s choice and Nina’s explosive accusation leave the family deeply split.
