‘The Affair Was Just the Beginning’ Opens With a Polished Life Coming Apart

“The Affair Was Just the Beginning” arrives with the glossy surface of a family drama and the sharp edge of a dark comedy. Its opening episodes introduce two neighboring households whose homes, careers, and public images suggest stability. The series quickly makes clear that each polished detail is covering a fault line.

Kim Hye Soo plays Kyung Hee, a self-made interior-design influencer whose online success has reshaped her family’s circumstances. Her husband Jae Hong, played by Kim Ji Hun, is a working actor, and the pair are raising their daughter Ye Ji while settling into an affluent new neighborhood. Kyung Hee’s confidence is earned: she has turned visibility and hard work into financial comfort. Yet the move also places her among people whose influence comes from a different kind of social standing.

Across the way is Soo Jung, a dermatologist portrayed by Cho Yeo Jeong. She is in the middle of a bitter custody dispute with her estranged husband Bo Sung and is trying to keep her clinic afloat. Where Kyung Hee is outgoing and eager to build a place for her family, Soo Jung is guarded, controlled, and reluctant to accept intimacy. Their contrasting styles give the premiere an immediate tension that goes beyond a simple clash of neighbors.

A polished world with cracks underneath

The drama uses its setting to explore the distance between appearance and reality. Kyung Hee’s life looks aspirational: a successful personal brand, a beautiful home, and a family that appears united. But she remains sensitive to the possibility that popularity cannot purchase belonging. Her efforts to connect with Soo Jung include using her network to help bring attention to the struggling clinic, a gesture that is partly practical but also sincerely meant to create goodwill.

That goodwill becomes more complicated as the story exposes a betrayal inside Kyung Hee’s own marriage. Jae Hong’s affair with Soo Jung shifts the drama’s focus from the discovery of infidelity to its wider consequences. The relationship threatens not only a marriage, but the fragile set of arrangements that allow both families to present themselves as functional.

The affair is treated as a catalyst rather than the entire story. The premiere is more interested in what people conceal, how they justify their actions, and what happens when private failures collide with public reputations. The series also draws humor from the increasingly strained attempts to maintain control, placing domestic discomfort beside moments of near-absurd escalation.

Kim Hye Soo anchors the early episodes

Kyung Hee gives the show its emotional center. Kim Hye Soo plays her as capable and ambitious without making her confidence feel effortless. Kyung Hee understands that online relevance requires constant reinvention, and she has built a life around staying visible and useful. At the same time, she trusts the people closest to her and believes the success she has created has made her family secure.

That mixture of resourcefulness and trust makes the character’s position especially precarious. Kyung Hee is not presented as naïve; instead, she is someone whose attention has been directed toward holding together a demanding public and domestic life. As warning signs accumulate, the performance suggests how painful it will be for her to recognize that the image she has protected may not match the truth around her.

Cho Yeo Jeong brings an unsettled ambiguity

Soo Jung is initially framed as a woman under visible pressure, dealing with a contentious divorce, a resistant teenage daughter, and professional setbacks. The premiere gradually reveals a more forceful side to her. Her determination to shape her daughter’s future and her efforts to gain leverage in the custody fight raise uncomfortable questions about how far she is prepared to go when she feels threatened.

The story intensifies when the teenagers become connected to a sudden accident involving an investigator. That turn gives the adults more than one secret to manage and raises the stakes beyond the affair itself. Both Soo Jung and Jae Hong now have reasons to protect a version of events that may not hold for long.

With its focus on status anxiety, family obligation, and the performances people give to the outside world, “The Affair Was Just the Beginning” establishes a tense foundation. The early episodes leave the central question open: when the facades finally collapse, who will be willing to take responsibility for the damage?
