Xie Mingtang has been married to the Marquis of Jing’an’s household for three years, enduring her husband’s coldness, her mother-in-law’s torment, and humiliation from his beloved first love. On the day she asks for a divorce, Pei Wang, the dangerously obsessive heir to the Regent’s household, arrives with three-year-old Pei Suisui in his arms and reveals the truth: the child she was told had “died in infancy” is still alive.
Xie Mingtang leaves the marquis’s household, reclaims her dowry, investigates the truth behind her child’s abduction, settles accounts with Shen Wanrou and the marquis’s household, restores the Xie family, and uncovers the old case surrounding the deaths of her father and brothers in battle. Pei Wang protects her every step of the way, but never takes control away from her. As they investigate the case, protect the child, and seek revenge, they gradually build trust and affection.
Gu Cheng’an goes from arrogant and indifferent to consumed by regret. He watches Xie Mingtang transform from an abandoned wife in the marquis’s household into the Regent’s heir’s future wife, and realizes there is no way back.
In the end, the old case involving the Xie family is overturned, the marquis’s household falls into ruin, Shen Wanrou is brought to justice, and Pei Wang is cured of his poison. Xie Mingtang and Pei Wang marry, and Suisui takes her mother’s hand as they walk toward a home that is truly theirs.
