As the sun rises on a new episode of "Cinderella at 2 AM," we find our protagonists, Seo Joo-won and Ha Yoon-seo, still reeling from the aftershocks of their recent breakup. Episode 4, aptly named "The Business Trip," delves into the complexities of their post-breakup emotions and the unexpected twists that arise as they attempt to navigate their professional lives.
The episode commences with a series of reminiscences, as both Joo-won and Yoon-seo find themselves lost in memories of their shared past. Their attempts to avoid each other at the office are futile, as fate seems to have other plans. Yoon-seo's life takes an unexpected turn when she starts receiving cryptic text messages from an unknown number, each one more unsettling than the last. The sender's insistence on not being able to forget her leaves Yoon-seo with a nagging suspicion that Joo-won might be behind this mysterious communication.
Her suspicions are further fueled when she discovers that Joo-won possesses two mobile phones, leading her to confront him in a scene brimming with tension and embarrassment. The misunderstanding is quickly resolved when Yoon-seo learns that the second phone is merely a company test sample, not the device of a lovesick ex-boyfriend.
This revelation leads to a heart-to-heart conversation with I-rae, Yoon-seo's confidante, who advises her to call the unknown number. The call reveals a case of mistaken identity, as the sender had been inadvertently texting Yoon-seo. This turn of events brings a moment of levity to an otherwise somber narrative.
Meanwhile, Yoon-seo's relationship with her brother, Ji-suk, sees a significant development. Their previous conflict comes to a resolution as Ji-suk agrees to take responsibility for his actions and apologize to his classmate. This marks a pivotal moment in Ji-suk's personal growth, as he also decides to prepare for a competitive exam, despite his lack of a clear goal.
As Yoon-seo and Ji-suk's relationship reaches a new understanding, an unexpected encounter with Joo-won leads to a revelation that Yoon-seo and he have parted ways. Joo-won's offer to change offices to ease Yoon-seo's discomfort is a testament to his consideration, even as their personal and professional lives become increasingly intertwined.
The episode also sheds light on the strained relationship between Joo-won's brother, Si-won, and his wife, Mi-jin. Si-won's frustration with his wife's return from France is palpable, as he has grown accustomed to the solitude of his bachelor life. A flashback reveals the origins of their arranged marriage, set against the romantic backdrop of Paris, highlighting the stark contrasts between the two.
As Yoon-seo gears up for a business trip, the mysterious text messages continue to plague her, adding an air of mystery and frustration to her already tumultuous emotional state. A phone call to the sender unleashes Yoon-seo's pent-up emotions, providing a window into her inner turmoil. The anonymous texter is revealed to be a painter with a keen interest in Yoon-seo, adding a new layer to the story.
A car accident involving Yoon-seo's colleague forces Joo-won to step in, offering a ride to the business meeting. The ensuing car ride is fraught with awkward moments, as Joo-won's phone mistakenly connects to Yoon-seo's via Bluetooth, and a slip of the tongue leads to him accidentally calling her "honey." Despite the embarrassment, the two arrive at their destination, where Yoon-seo takes pride in Joo-won's professional progress.
Back at home, Si-won's discontent grows as he learns of his wife's plans to extend her stay in Korea, signaling an end to his newfound freedom.
The episode reaches its climax at the opening ceremony, where Yoon-seo makes a life-altering decision to quit her job. She realizes that it is impossible for her and Joo-won to continue working together without further complicating their already delicate situation. Her decision leads to a late-night conversation with Joo-won, where he, in turn, decides to ask his mother to send him abroad.
Joo-won's request sets off a chain of events, as he learns of the expectation to take over for Si-won, whose wife will be in charge of business expansion. A heated argument with his mother leaves Joo-won with nowhere to turn but to Yoon-seo, who provides a comforting embrace.
The episode concludes with a dramatic twist, as Yoon-seo's colleagues and I-rae arrive at her place, catching Joo-won and Yoon-seo in an intimate moment. The exclamation of whether the couple has rekindled their romance leaves viewers hanging on the edge of their seats, eagerly anticipating the resolution of this tangled web of love and deception.
"The Business Trip" is a masterful portrayal of the intricacies of human relationships and the often blurred lines between love, duty, and personal growth. It is a poignant reminder that life is full of unexpected turns and that even the most well-intentioned decisions can lead to unforeseen consequences. As the credits roll, we are left with a sense of longing for the characters' happiness, despite the challenges that life continues to throw their way.
