Fairy Ye Tong is banished for stealing immortal peaches, reincarnated as Luna Ye, the long-lost legitimate returned daughter of a marquis household. She carries a unique superpower: all her family members can hear her inner monologue. She reveals in advance the tragic fate that will befall her entire family, exposes the murderous plot of the deadbeat father, scheming aunt and impostor noble daughter who swapped the children at birth. Her mother, elder brothers and elder legitimate sister are awakened by her inner voice, turning from forbearing wronged family members to fight back fiercely. With her immortal powers, she teams up with Jasper Gu, the town duke's son with a hidden identity, to take down villains, resolve crises, root out all conspiracies in the marquis household, rewrite the family's tragic fate. The two fall in love mutually and rise to power together, with both satisfying revenge and sweet romance plotlines running in parallel.
