Kim Hye Soo Leads Dark Comedy The Affair Was Just the Beginning Ahead of July Premiere

Kim Hye Soo is preparing to return to television in a black comedy that begins with a familiar domestic scandal and quickly pushes it into more unpredictable territory. The Affair Was Just the Beginning has released new teaser materials ahead of its July 31 premiere, placing two neighboring families at the center of a story about public image, private collapse, and the consequences of a secret too large to hide.

The drama centers on Kyung Hee, played by Kim Hye Soo, a popular influencer who has built a glossy life around the image of a happy marriage and an aspirational home. Her husband Jae Hong, played by Kim Ji Hun, appears to complete that carefully managed picture. Across the way, however, another household is already in crisis. Cho Yeo Jeong plays Soo Jung, a doctor caught in a bitter divorce and custody dispute with Bo Sung, portrayed by Kim Jae Chul.

The new posters frame the series around contrast. Kyung Hee’s home is presented with bright energy, bold color, and the kind of visual polish expected from a woman who has turned her lifestyle into a brand. Yet the image is disrupted by a strangely placed electric drill and the pointed line, An affair would have been better. The detail suggests that the story will not stop at marital betrayal, and that the scandal threatening Kyung Hee may be only the simplest version of the truth.

Two Homes, Two Crises

Soo Jung’s poster takes a different approach. Rather than colorful confidence, it leans into controlled elegance, with the character holding a wine glass while a separate tagline states, A divorce lawsuit would have been better. That contrast gives the show its early dramatic engine: one woman appears to have the perfect domestic life while another is fighting to keep her family from falling apart, but both are standing closer to disaster than they realize.

The teaser expands that setup by first showing Kyung Hee and Jae Hong in what looks like a smooth, harmonious routine. Kyung Hee’s backstory adds another layer to the image. She is described as a self-made figure who rose from a modest single-room residence to a luxury home, making her current status something she has fought to achieve and must now protect. In a social media-driven world, that kind of success is not only personal. It is also public property, always exposed to judgment.

Soo Jung watches that apparent happiness from the outside while dealing with her own unstable circumstances. Her conflict with Bo Sung is not simply a romantic breakup but a custody battle, which raises the emotional stakes and gives the character an immediate reason to resent, envy, or question the polished life next door. The show appears to use that proximity between neighbors as a pressure cooker, letting private problems spill across the boundary between two families.

A Scandal That Opens Into Something Bigger

The trailer then shifts from domestic observation to chaos. Kyung Hee begins to spiral after encountering rumors about her husband’s affair, a revelation that could damage both her marriage and the carefully constructed identity that supports her career. Soo Jung, meanwhile, reacts in shock after witnessing something disturbing, suggesting that she may become pulled into Kyung Hee’s crisis through more than simple curiosity.

What makes the premise notable is the drama’s refusal to treat the affair as the final twist. The title itself signals escalation: the affair is only the beginning, and the materials released so far repeatedly imply that a larger secret will make ordinary scandal feel almost manageable by comparison. That approach positions the series within a growing wave of Korean dramas that mix genre tones, using comedy, suspense, and social satire to examine reputation and family life.

Kim Hye Soo’s casting also gives the project a strong center of gravity. Known for commanding roles that balance sharp intelligence with emotional force, she is well suited to a character whose polished control begins to crack under public and private pressure. Cho Yeo Jeong’s role as Soo Jung offers a complementary form of tension, rooted less in brand management and more in legal conflict, parenting stakes, and the exhaustion of a failing marriage.

With Kim Ji Hun and Kim Jae Chul rounding out the two households, The Affair Was Just the Beginning is setting up a four-person collision in which no one appears fully secure. The newly released teasers do not reveal the central secret, but they make the show’s direction clear: this is not a straightforward infidelity drama. It is a darkly comic look at how fast a perfect image can collapse when the wrong people see what was never meant to be seen.

The series is scheduled to premiere on July 31 at 8 p.m. KST and will be available through Viki. For viewers drawn to character-driven Korean dramas with a mix of marital tension, social satire, and mystery, the latest teasers suggest a story designed to make the first scandal feel like only the opening move.
