Kim Hye Soo Leads Twisted Black Comedy The Affair Was Just the Beginning

Kim Hye Soo is returning to the small screen with a sharply comic mystery built around marriage, status, and the hazards of living too close to other people’s secrets. The upcoming drama The Affair Was Just the Beginning has introduced its principal characters through new trailers and posters, setting up a black comedy in which two neighboring couples are pulled into a scandal that grows far beyond the first suspicion of infidelity.

The series centers on Park Kyung Hee, played by Kim Hye Soo, a self-made interior design influencer and chief executive whose life appears almost impossibly polished from the outside. She has a large online following, a coveted creator award, a younger husband, and a home designed to project taste, wealth, and control. The early character material frames Kyung Hee as someone who has worked hard to build every part of that image, which makes the first crack in her marriage feel especially threatening.

That crack arrives when rumors begin to circulate about her husband, Lim Jae Hong. Rather than dismissing the whispers, Kyung Hee begins watching him herself, determined to confirm what is happening with her own eyes. The premise turns a familiar domestic suspicion into something broader: a story about a woman whose personal life, brand identity, and business reputation are all tied to the same carefully arranged picture of success.

A Marriage Built For Public Display

Kim Ji Hun plays Jae Hong, Kyung Hee’s younger husband, who presents himself with easy charm and a celebrity-adjacent persona. He uses a stage name and carries himself like someone accustomed to being seen, but the trailers suggest that much of his confidence depends on staying within the version of events he can still control. His cheerful tone shifts when questions about the woman next door become too pointed, hinting that his genial image may be more fragile than it first appears.

The comedy appears to come from the distance between what these characters say and what the audience can sense underneath. Jae Hong insists he is devoted to his family and that his connection to the neighbor is harmless. Kyung Hee wants to believe the life she built remains intact. Yet the drama’s title signals that the suspected affair is not the endpoint. It is only the incident that opens a larger chain of consequences.

Cho Yeo Jeong plays Ahn Soo Jung, the neighbor at the center of Jae Hong’s defensive explanations. Soo Jung is an elegant dermatologist and mother who seems determined to keep boundaries between her family and the newly arrived couple next door. Her words suggest restraint, but her careful distance also creates suspicion. She is not written simply as an object of jealousy; she appears to be guarding priorities of her own, particularly her child’s future.

Two Families, One Escalating Secret

Kim Jae Chul rounds out the central adult cast as Joo Bo Sung, Soo Jung’s estranged husband and fellow dermatologist. He is already separated from Soo Jung and in the middle of a divorce, giving the drama a second unstable marriage to mirror Kyung Hee and Jae Hong’s unraveling household. His interest in Kyung Hee’s interior design work introduces another potential crossing of personal and professional lines, suggesting that the adults may become entangled in ways that are emotional, strategic, and socially dangerous all at once.

The drama’s structure looks designed around contrast. On one side is Kyung Hee’s glossy influencer world, where a beautiful home and affectionate husband help sell an aspirational life. On the other is Soo Jung and Bo Sung’s colder domestic fracture, where a divorce is already underway and the focus has narrowed to protecting a child’s path forward. When the two households collide, the story can use comedy to expose how much performance sits inside marriage, parenting, professional respectability, and neighborhood etiquette.

The younger generation also appears poised to matter. Posters introduce Kyung Hee and Jae Hong’s daughter Ye Ji, played by Jeon Si Hyun, and Soo Jung and Bo Sung’s daughter Min Seo, played by Do Yeong Seo. Their contrasting images add another layer to the premise: the adults may be preoccupied with status and suspicion, but the consequences of their choices are likely to land on their children as well. That gives the drama room to shift from social satire into something more uneasy.

Premiere Date And Viewing Details

The Affair Was Just the Beginning is scheduled to premiere on July 31 at 8 p.m. KST and will be available on Viki. The cast list gives the project immediate attention: Kim Hye Soo brings a commanding presence to a role built around pride and collapse, Kim Ji Hun plays against the smoothness of a husband trying to contain rumor, and Cho Yeo Jeong’s involvement strengthens the drama’s promise of layered social comedy.

For viewers, the main draw is not simply whether an affair happened. The more compelling question is what the suspicion exposes once everyone starts protecting their own version of the truth. By placing influencers, doctors, spouses, neighbors, and children inside the same pressure cooker, the series is positioning itself as a darkly funny look at how quickly a perfect life can become evidence in someone else’s story.
