Two modern sisters wake up inside a painting—as rival princesses sent into a political marriage. One prince watches them like enemies. The other plays charm like a weapon. A slow-burn marriage turns into something neither of them planned.

This episode tells the story of Su Wanwan, a modern million-fan livestreamer, who accidentally travels through time and becomes the consort of Prince Jing of the Great Liang Dynasty. On her wedding night, Prince Jing, Xiao Beichen, eagerly anticipates his consort's advances. To his surprise, Su Wanwan is hiding in the room, counting her dowry and amusing herself with her modern livestreaming patter. Xiao Beichen pushes the door open, and Su Wanwan instantly switches to her "drama queen mode," using her professional livestreaming skills to handle the probing of the cunning prince. Xiao Beichen becomes intensely interested in this consort whose personality has drastically changed, believing she is playing a game of "playing hard to get." While outwardly compliant, Su Wanwan internally complains. Before successfully seeing the prince off, she doesn't forget to ask where to collect the "monthly silver allowance" for the manor, showcasing her money-loving and extremely survival-driven modern soul.

Two modern sisters wake up inside a painting—as rival princesses sent into a political marriage. One prince watches them like enemies. The other plays charm like a weapon. A slow-burn marriage turns into something neither of them planned.

On their wedding night, brothers Xiao Jingyuan (the First Prince) and Xiao Beichen (the Second Prince) meet in the study to pry into the backgrounds of their new wives. Xiao Jingyuan complains to his brother that Lu Qingzhi is not here for a "marriage alliance" but for a "divorce." Xiao Beichen teases Xiao Jingyuan about his methods for dealing with women but learns that Lu Qingzhi can not only easily unlock heavy chains with a hairpin but also deduce his martial arts style from Xiao Jingyuan's gunshot wound. The two realize these two princesses from Mobei are far from ordinary, their schemes unfathomable, and decide to go to the palace tomorrow to watch a good show.

This episode depicts the first morning after Lu Qingzhi and Su Wanwan's arranged marriages, where they privately lament their "bookworm" and "CEO-type" husbands using modern perspectives. Afterward, the two women enter the palace to express their gratitude to Consort Rong. Consort Rong sets a political trap by inquiring about the strengths and weaknesses of the Liang border army versus the Mobei cavalry. Lu Qingzhi skillfully navigates this with a dialectical and objective answer, while Su Wanwan wins Consort Rong's favor through high emotional intelligence and flattery. Just as the mother-in-law and daughters-in-law are enjoying a harmonious atmosphere, a maid suddenly bursts in, accusing them of having secret border reports of colluding with the enemy found in their dowry chests. The peaceful situation is instantly shattered by a life-or-death crisis.

Consort Li attempts to frame Lu Qingzhi and Su Wanwan as spies using forged letters, but Lu Qingzhi skillfully points out a logical flaw in the letter regarding the number of troops stationed at Hutu Gorge, turning the tables publicly. Empress Rong, as the mother-in-law, sees through Consort Li's dirty tactics and protectively defends her daughter-in-law, ordering the maid spreading rumors to be beaten to death. After the crisis is averted, Lu and Su receive generous gifts from Empress Rong. In private, they plan to save up five hundred taels of silver and escape the capital for a life of freedom. However, brothers Xiao Jingyuan and Xiao Beichen, wary of the women's profound schemes, begin to harbor murderous intent towards them.

This episode details Lu Qingzhi's discovery of a severe vulnerability in Prince Rui Xiao Jingyuan's Black Wind Pass defense map. If executed as is, it would lead to the innocent deaths of tens of thousands of soldiers. Knowing that "Living Yama" Xiao Jingyuan wouldn't easily believe her, Lu Qingzhi, after consulting with her best friend Su Wanwan, decides to take extreme measures. Su Wanwan will try to seduce and drug the Second Prince Xiao Beichen to steal his study key and secretly alter the defense map. Dressed in a sheer, long gown, Su Wanwan attempts to drug him under the guise of delivering wine. Xiao Beichen sees through her intentions at a glance but deliberately flirts to test her. Ultimately, Su Wanwan succeeds in drugging Xiao Beichen, temporarily resolving the crisis and advancing the plan to its next stage.

Xiao Jingyuan catches Lu Qingzhi "stealing" defense plans. Instead of panicking, Lu Qingzhi, with her remarkable military talent, points out fatal flaws in the plans and optimizes them on the spot, deeply shocking Xiao Jingyuan with her brilliance. Faced with Xiao Jingyuan's further interrogation and threats of torture, Lu Qingzhi recalls the "love tricks" her modern best friend Su Wanwan taught her. At the brink of death, she suddenly declares loudly in front of everyone her "love for the Prince," successfully stunning the menacing Xiao Jingyuan and shifting the atmosphere from intense confrontation to awkward ambiguity.

This episode showcases interactions filled with probing and strategizing between two pairs of princes and their consorts. Su Wanwan attempts to seduce Prince Jing, Xiao Beichen, with a "deep declaration of love," but her poor acting is cruelly seen through by Xiao Beichen, who then expels her. Afterward, Xiao Beichen discusses Su Wanwan's true motives with his confidant, suspecting she is deliberately acting to help her best friend, Lu Qingzhi. Meanwhile, Lu Qingzhi is caught by Prince Rui, Xiao Jingyuan, while trying to orchestrate a match by stealing a key. She attempts to diffuse the tension by acting familiar, claiming they are "family," but is met with stern questioning and suspicion from Xiao Jingyuan. The suspicion of the two sisters acting as "operatives" remains unaddressed, and their relationships with the princes are also a game played under the shadow of political maneuvering.

This segment focuses on a high-stakes confrontation between Prince Xiao Beichen of Daliang and his consort Su Wanwan. Suspecting Su Wanwan of being an enemy spy, Xiao Beichen threatens her with a chokehold and uses cruel methods to intimidate her. However, Su Wanwan, possessing memories of her past life and a quirky personality, quickly retaliates after a brief life-or-death crisis, leveraging her "social butterfly" nature and modern mindset. She transforms Xiao Beichen's humiliating provocations into an offensive of "主动侍寝" (proactively offering to serve him in bed), drafts a "consort service agreement" with monetary penalties, and, by spewing modern slang and nonsensical poetry, turns the tense interrogation scene into an embarrassing battlefield that forces the cunning prince to flee in disarray. Su Wanwan successfully resolves her identity crisis with her "crazy" actions and gains the psychological upper hand.
