The military man wanted to arrange a marriage exchange, but then she married his superior officer

Liu Qingyue is reborn thirty years into the past, returning to the moment her tragic life originally began. In her previous existence, she was deceived by her younger half-sister, Liu Wanwan, and her fiancé, Zhou Heshan. Liu Wanwan pushed Liu Qingyue into a lake to ruin her reputation, allowing Zhou Heshan to break their engagement and marry Liu Wanwan instead. Liu Qingyue was subsequently sent to a remote island with the army, where she suffered humiliation and eventually died of cancer after a loveless marriage to Lu Fengting, a man who had saved her twice. Armed with memories of her past life and a mysterious spatial necklace containing a farm and storage capabilities, Liu Qingyue resolves to change her fate and exact revenge on those who wronged her.

The story opens at the lakeside where Liu Wanwan attempts to replicate her past scheme by pushing Liu Qingyue into the freezing water. However, the reborn Liu Qingyue anticipates the trap and publicly accuses Liu Wanwan of attempting murder to seize her fiancé. When Lu Fengting, a navy officer, rescues her, he offers to take responsibility for her ruined reputation. Liu Qingyue refuses his offer, publicly defending her fiancé Zhou Heshan to set a trap for his future hypocrisy. Back home, she confronts her biased father and stepmother, Wang Chunhua, who favor Liu Wanwan. Utilizing her spatial abilities, Liu Qingyue secretly empties the household of all valuables, food, and savings overnight, leaving her family in chaos and forcing them to rely on borrowed goods. This act severs her financial dependence on the family and weakens their ability to control her.

Liu Qingyue travels to the military island with Liu Wanwan, who insists on accompanying her to secure her marriage to Zhou Heshan. During the train journey, Liu Qingyue displays sharp observational skills by detecting a couple trafficking a drugged child. She reports them to the railway police, leading to their arrest and earning the respect of fellow passengers. Upon arriving at the island, Zhou Heshan publicly humiliates Liu Qingyue, claiming her reputation is ruined and demanding she step aside for Liu Wanwan. Liu Qingyue counters by exposing the inconsistencies in his story and accusing Liu Wanwan of pushing her into the lake. The confrontation escalates when Liu Wanwan falls and clutches her stomach, leading Liu Qingyue to deduce that Liu Wanwan is pregnant with Zhou Heshan’s child.

A military wife confirms Liu Wanwan’s pregnancy through pulse diagnosis, revealing the affair and the premeditated nature of the scheme. Zhou Heshan attempts to strike Liu Qingyue in anger but is stopped by Lu Fengting, who arrives as the deputy regiment commander. Lu Fengting insists on reporting Zhou Heshan’s misconduct to the brigade commander. Faced with the exposed scandal, Liu Qingyue refuses to be a victim. She confronts the brigade commander, demanding justice for the betrayal and the false accusations against her character. The narrative establishes her determination to dismantle the lives of her enemies while securing her own independence and future, marking a decisive shift from her passive past-life existence to an active, strategic protagonist.
