At the Empress Dowager's birthday banquet, the once obese Consort Ying, Chu Ying, makes a stunning appearance with her post-weight loss dance, shocking everyone. Seizing the opportunity, she publicly confronts her rival Consort Yang, with whom she had a bet, and uses Emperor Ye Haotian's words to confirm the wager, successfully forcing Consort Yang to kneel and kowtow in front of everyone, completing a brilliant comeback. Afterwards, when Ye Haotian is alone with Chu Ying, while he expresses concern for her body due to her drastic weight loss, he also sharply questions her inner transformation and whether her heart still belongs to someone else. Their relationship unfolds amidst new tests and games.

The episode opens with Emperor Ye Haotian questioning Consort Ying (Chu Ying) about her uncharacteristic closeness, recalling her past strong resistance due to a beloved. Chu Ying, possessing a modern soul, quickly changes her demeanor to handle the crisis, flattering the emperor with sweet words to deceive him. However, the emperor remains suspicious. As Chu Ying curses the emperor internally, her past love, Prince Ming Ye Mingli, suddenly appears and calls her by her childhood nickname, plunging her into an even more complex and dangerous situation.

The episode opens with a flashback from protagonist Chu Ying's memories, revealing that the original body owner, "Fat Concubine," once deeply loved Prince Ye Mingli, who placated her with the lie of marrying her after successfully seizing power. Back in reality, the amnesiac and thinner Chu Ying realizes Ye Mingli is the murderer who used and killed the original owner. Facing Ye Mingli's probing, Chu Ying feigns amnesia and distances herself from him. Subsequently, Chu Ying has another flashback, overhearing a secret plot between Ye Mingli, Consort Yang, and the Empress Dowager: they used the original owner to seize her father Chu Liang's military power to usurp the throne. The original owner, upon realizing she was merely a pawn, was silenced, revealing to Chu Ying the grave crisis she is in.

Transmigrated as Concubine Ying, Chu Ying is determined to win Emperor Ye Haotian's favor for survival. However, Ye Haotian, though remembering her kindness from their youth, harbors doubts due to her drastic personality change and her past affections for someone else. That night, Chu Ying takes the initiative to help Ye Haotian change his clothes, confessing her sincerity and declaring she has awakened and wishes to treat him wholeheartedly. Facing Ye Haotian's accusation of being a "substitute," Chu Ying presses forward, using words and intimate gestures to test him. Ultimately, she provokes him with the remark of being "close to other men," igniting his jealousy, and he forcefully kisses her. Unexpectedly, after the kiss, Chu Ying suddenly coughs up blood and collapses, causing a sudden plot twist.

The imperial physician diagnoses Concubine Ying with pregnancy, but Emperor Ye Haotian, knowing he has never consummated their marriage, flies into a rage, deeming her unchaste. Fueled by the Empress Dowager and Consort Yang, Ye Haotian imprisons the defenseless Concubine Ying. In prison, Concubine Ying (Chu Ying) suspects she was framed by the Empress Dowager, who manipulated her into displaying a false pregnancy pulse. Meanwhile, Ye Mingli, who covets the throne, visits her in prison, makes lewd remarks, and attempts to assault her, implying his involvement in the matter. On the other side, Ye Haotian grieves alone, tormented by the betrayal he feels.

In front of Emperor Ye Haotian, she exposes the truth of being drugged and framed by the Empress Dowager. To make the suspicious Emperor believe her, Chu Ying forces him to drink the aphrodisiac wine and summons the imperial physician to check his pulse, allowing the Emperor to experience a "happy pulse" himself. At this point, the Empress Dowager and Ye Mingli, to cover up their crimes, arrange for the palace maid who administered the drug to "commit suicide" as a scapegoat. Although the Emperor decrees Chu Ying innocent, she knows this is merely a tactic of her enemies to sacrifice a pawn. Determined to gain the Emperor's trust, she vows to seek revenge on the Empress Dowager, Ye Mingli, and others.

In this episode, Chu Ying designs a "trust fall" game to gain Emperor Ye Haotian's trust.
