In the highly anticipated season finale of "Bitch X Rich," episode 10 picks up right where we left off, with Hye-in captivated by the distressing video of Hae-in engaging in intimacy with Woo-jin. She reaches into her drawer, pulling out Hae-in's necklace, her mind racing to comprehend the intricate web of secrets weaving through the school's corridors.
The following day, an unexpected invitation arrives when Do-eon approaches Hye-in, extending a heartfelt request for her to accompany him as his plus-one to Woo-jin and Yul-hee's fifth-anniversary gala.
Secluded in an abandoned restroom, Si-eun corners Hye-in, dragging her into a clandestine confrontation. With steely resolve, Si-eun holds the threat of exposing Hye-in's compromising video over her head, yet Hye-in stands firm, insisting Je-na is not the perpetrator behind Hae-in's plight. Si-eun's gaze falls upon a pen drive bearing Hae-in's name, revealing a bombshell: Hae-in had been blackmailing Je-na, which ultimately led to Je-na's tragic push from the rooftop – all for the sake of protecting Yul-hee. Flashbacks haunt the space, showing Hae-in trembling in fear after receiving a chilling video from an anonymous source.
Present-day Si-eun unloads the details, revealing Hae-in's leverage over Je-na involved exposing her father's infidelity. With a final sinister warning to expose Hye-in's video too, Si-eun slips away, leaving Hye-in to fend for herself. Overhearing their exchange from within the stall, So-mang emerges, offering to aid Hye-in by taking the matter to the authorities. But Hye-in, jaded by the system, rejects his offer. In jest, So-mang suggests praying to God might be Hye-in's only hope against Si-eun's menacing intentions.
The evening unfolds at Woo-jin and Yul-hee's anniversary bash, where Hye-in, by Do-eon's side, navigates the opulent celebration marking five years of the couple's union. Seeking fresh air, Do-eon and Hye-in wander outside, Hye-in probing Do-eon's perception of Hae-in. He portrays her as a gentle, innocent soul, unaware of the dark truths Hye-in holds close.
At the party, Hye-in's suspicions toward Yul-hee deepen, prompting her to inquire about Yul-hee's necklace. Je-na chimes in, explaining its exclusivity yet hinting at its attainability for those with connections, despite the waitlist. As tensions flair, Do-eon and Je-na's long-standing friendship crumbles into an acrimonious spat. Je-na accuses Do-eon of abandoning her for Hae-in, clarifying that her bullying wasn't fueled by Hae-in's poverty but by her inherent malice. Je-na drops another bombshell, exposing Hae-in's extortion schemes, using people's secrets to milk money from them, including Woo-jin. In a climactic revelation, Je-na confronts Yul-hee with Woo-jin's affair with Hae-in, sparking a fiery altercation while Yul-hee weeps in despair.
In a poignant flashback, Hae-in's conversation with Je-na atop the rooftop took a sinister turn as he resorted to threats and attempted extortion, demanding money from her. Moreover, Hae-in's despicable actions extended further; he even dispatched a spy cam footage to Woo-jin, seeking financial gain from him as well. During their rooftop discourse, Hae-in remarkably justified Je-na's relentless pursuit of success, asserting that there was nothing wrong with striving to reach the pinnacle by any means necessary.
Later, in the present timeline, Yul-hee experiences an emotional meltdown in private with Je-na, who is tormented by her guilt for revealing the truth. Suddenly, Yul-hee's demeanor shifts drastically as she confesses that she was already cognizant of Woo-jin's infidelity. With a twisted sense of empowerment, she boasts that Woo-jin is now firmly in her grasp and will never contemplate leaving her, as she plans to "forgive" him for his betrayal.
Turning the narrative to a chilling revelation, that very evening, Hye-in leads Je-na to her home and unveils a necklace, a keepsake she gathered from Hae-in's grasp on the fateful night he plummeted from the rooftop. Hye-in's revelation shatters any remaining doubt: it was Yul-hee who shoved Hae-in off the edge, motivated by jealousy over his affair with her boyfriend. A subsequent flashback unfolds, depicting Yul-hee's arrival on the rooftop after Je-na's departure. In a fierce altercation, the two girls grapple and扯扯hair, culminating in a harrowing accident where Yul-hee, amidst the struggle, inadvertently sends Hae-in tumbling over the edge. As Hae-in falls, his grasp tightens around Yul-hee's necklace, marking the exact spot where Hye-in now stands, haunted by the memory.
The climax of "Bitch X Rich" unfolds with Hye-in arriving at school the following day, her hopes pinned on So-mang resolving her issue with Si-eun. Instead, she receives a chilling text from Si-eun, granting her until midnight to expose Je-na to the school director. Meanwhile, a girl adorned with identical luxury footwear steps into Hee-seo’s cabin, adding another layer of intrigue.
That fateful night, tension escalates between Yul-hee and Woo-jin, culminating in a fierce argument. Yet, amidst the storm, she oddly "forgives" him for his infidelity, a decision as perplexing as it is unsettling.
Hye-in, intent on a heart-to-heart with Si-eun, requests her to wait at school. Unbeknownst to Hye-in, Si-eun has ascended to the rooftop, poised to unleash the damning video. But before she can, a shocking force propels Si-eun off the edge, mirroring Hae-in's tragic fall. Hye-in, frozen in the exact spot where she once witnessed Hae-in's plunge, now bears witness to this harrowing repetition.
As the season draws to a close, the macabre image of Si-eun's blood trickling from her head haunts the screen. Hye-in’s voice trembles as she declares with conviction that Cheongdam International High School is undeniably cursed, the final scene etched in viewers' minds with an eerie blend of horror and intrigue.
