Episode 6 of "Bitch X Rich" resumes with the entire school in hot pursuit of Hye-in, who finds sanctuary in the art room where she encounters Oh Si-eun. With concern etched on her face, Si-eun notices Hye-in's bare feet and offers a pair of sneakers lying carelessly around the room. Grateful for the gesture, Hye-in accepts the shoes and learns from Si-eun that her photograph has been plastered all over the school forum, thanks to Je-na's orchestrated witch hunt.
While waiting for the student mob to dissipate, the two girls engage in a heartfelt conversation about Je-na and the Diamond Club, a clique of wealthy bullies who terrorize their fellow students. Hye-in's mind drifts back to Do-eon's promise to come to her aid when she needed it most. She quickly texts him for help, but before she can reach safety, the students encircle her.
Defiantly, Hye-in threatens to record their bullying and report them to the police. However, the students remain unperturbed, confident that their families' wealth will buy off the authorities and squash any investigation. As they close in on her, Hye-in takes a daring leap from the second floor, only to be caught by Do-eon in a dramatic moment that prevents her from hitting her head on the ground.
Later, on her way home, Je-na receives distressing news from her henchmen, Yul-hee and Woo-jin, about Do-eon's heroism in saving Hye-in. Je-na's mood darkens further as she recalls her father's mistress ensnaring Mr. Baek and Do-eon being similarly trapped by Hae-in. When she arrives at dinner with Mr. Baek and his mistress, Je-na is seething with rage. Her fury intensifies when she learns that her father has proposed to the woman and asked her to marry him.
The mistress reveals that she is 12 weeks pregnant with Mr. Baek's child, prompting Je-na to storm out of the restaurant in a fit of anger. Back at school, Do-eon lends a helping hand to Hye-in, leading her to the rooftop where he tenderly attends to her wounds. He confesses his love for Hae-in and admits that he was powerless to help her when she met with an accident. However, he stresses that he wants to be there for Hye-in now.
As Hye-in ponders her life's ambition to amass wealth while other girls around her aspire to be like Cinderella, she comes to a realization. She understands that Cinderella's fortune stemmed from her marriage to a wealthy prince and wonders if she too could enchant Do-eon into becoming her prince charming.
However, Do-eon inquires about the accident with Hye-in, his curiosity piqued about whether she caught a glimpse of her assailant who had pushed her off the roof. Hye-in, dawning upon the realization that Do-eon's kindness stemmed from a need for her assistance, rises to her feet, intending to depart. Do-eon persuades Hye-in to pretend to be his girlfriend, hoping to shield her from further bullying by their fellow students.
The following day, as Hye-in steps out of Do-eon's car, their intertwined hands astound the entire student body. Intrigued, the girls at school pepper Hye-in with questions about her relationship with Do-eon, marveling at how someone as insignificant as her had managed to enchant the director's son. Among them, Do-eon's friend and fellow Diamond Club members inquire if the rumors of their dating are true, to which Do-eon firmly warns them to stay clear of Hye-in.
Elsewhere, in the deserted women's restroom, So-mang confronts Hye-in, probing into her connection with Do-eon. Panicked, she dashes outside, leaving So-mang puzzled and inquisitive.
In class, Hye-in finds herself surrounded by the affluent girls who, now that she is labeled 'Do-eon's Girl', reintroduce themselves and invite her to a sorority party as a gesture of atonement for their earlier bullying. Sharing this invitation with Sun-joo, the latter insists that attending is a golden opportunity that should not be missed.
Agreeing to go, Hye-in borrows an exquisite dress from Na-yeon, promising to secure her admission to Cheongdam International High the subsequent year. Na-yeon emphasizes the importance of keeping the dress pristine and returning it in impeccable condition. On the night of the party, Sun-joo drops Hye-in off at the opulent restaurant.
Yet, upon entering, Hye-in feels out of sync amidst the opulence and elite company. Offered a glass of red wine, she nearly stains her borrowed white gown when the girls playfully, yet deliberately, "bump" into her. As Je-na makes her entrance, fate conspires as Hye-in, this time intentionally, spills wine on her dress.
As the episode draws to a close, Hye-in finally acknowledges that she was lured into the party only to fall prey to Je-na's bullying once more.
