Kim Hye Soo and Cho Yeo Jeong Lead Tense New Black Comedy The Affair Was Just the Beginning

Kim Hye Soo and Cho Yeo Jeong are moving into a tense neighborhood battle in the new drama The Affair Was Just the Beginning, a black comedy built around image, marriage, secrecy, and the social consequences of one family becoming entangled with another.

The series centers on two households living side by side but operating under very different forms of pressure. One is led by Park Kyung Hee, played by Kim Hye Soo, a self-made interior design influencer and company chief executive whose public life depends on taste, confidence, and the appearance of domestic success. The other is anchored by Ahn Soo Jung, played by Cho Yeo Jeong, an elegant dermatologist whose private life is already under strain because of a bitter divorce fight.

The premise turns on a sharp contrast between curated stability and emotional collapse. Kyung Hee and her husband Jae Hong, played by Kim Ji Hun, appear to represent the kind of successful couple that can be packaged, admired, and sold as an aspirational family image. Soo Jung and her ex-husband Bo Sung, played by Kim Jae Chul, bring a colder kind of tension into the story, with divorce proceedings, hidden conversations, and unresolved resentment shaping their side of the neighborhood.

A Neighborly Conflict With Public Image At Stake

Newly released materials for the drama frame Kim Hye Soo and Cho Yeo Jeong as opposing forces rather than simple neighbors. A poster places the two women in a wary face-off, suggesting that blame, suspicion, and self-protection will drive much of the early conflict. The drama’s title also signals that the affair itself may not be the largest problem; instead, it appears to be the incident that exposes deeper fractures already present in both families.

That framing gives The Affair Was Just the Beginning a distinctly contemporary hook. Kyung Hee’s life is not merely private. As an influencer and business figure, her home, marriage, and personal choices are tied to a carefully maintained brand. If her family life falls apart, the damage is not limited to emotional pain. It threatens credibility, status, and the social performance that supports her career.

Soo Jung’s position is different but equally combustible. As a dermatologist going through a difficult divorce, she enters the story with her own public poise and private instability. Early stills show her in moments of distress, while Bo Sung is shown maintaining a secretive phone call. Those details point to a plot in which each adult character is managing information, calculating risk, and trying to hold onto control while the truth keeps moving closer to the surface.

The Children Bring The Families Closer

The two families become more deeply connected when Kyung Hee’s daughter Ye Ji, played by Jeon Si Hyun, and Soo Jung’s daughter Min Seo, played by Do Yeong Seo, develop a friendship. That relationship changes the distance between the households. What might have remained a tense adult rivalry begins to enter family routines, shared spaces, and eventually a sequence of unexpected events that makes separation harder.

A dinner gathering appears to become one of the drama’s key pressure points. After several complications, the families end up at the same table, where social politeness gives way to subtle unease. The tension is especially visible between Soo Jung and Jae Hong, suggesting that the story will use ordinary domestic settings to reveal shifts in loyalty, attraction, resentment, and fear.

From there, the drama widens its conflict. Soo Jung is shown making quiet moves that could alter the direction of her divorce proceedings, while Jae Hong and Kyung Hee begin to face cracks in their own relationship after an unexpected incident. The images of Jae Hong holding his daughter with a complicated expression and Kyung Hee confronting the collapse of the life she built suggest that the series will not treat scandal as a single twist. Instead, it appears interested in how one revelation can restructure an entire household.

A Cast Built For Controlled Chaos

The casting gives the drama much of its appeal. Kim Hye Soo has long been associated with roles that combine authority, intelligence, and emotional force, making Kyung Hee a natural fit for a story about a woman whose control over her image begins to fail. Cho Yeo Jeong brings a contrasting presence as Soo Jung, whose elegance masks strategic pressure and personal volatility.

Kim Ji Hun and Kim Jae Chul round out the adult conflict by placing the two marriages at different stages of damage. Jae Hong’s position inside Kyung Hee’s polished life appears increasingly unstable, while Bo Sung’s role in Soo Jung’s divorce battle suggests a separate source of suspense. Together, the four characters create a structure in which every relationship can affect the others.

The Affair Was Just the Beginning premieres July 31 at 8 p.m. KST and will be available on Viki. With its mix of domestic suspense, dark humor, and social satire, the drama is positioning itself as more than a simple affair story. Its central question is how much of a family’s life can survive when the image everyone depends on starts to break.
