Park Kyung-hee (Kim Hye-soo) spent years turning a poor upbringing into an influencer empire and a Cheongnam-dong townhouse, so when rumors surface that her actor husband Lim Jae-hong (Kim Ji-hoon) is cheating, she tails him herself rather than wait for the truth to arrive secondhand. What she finds is worse than infidelity — Jae-hong disposing of a body, with their daughter Ye-ji somehow at the center of it. The premiere spends its entire runtime demoting an affair to the least of anyone’s problems.

Next door, dermatologist Ahn Soo-jung (Cho Yeo-jeong) is fighting her own war — a custody battle against ex-husband Joo Bo-sung (Kim Jae-chul) that’s already turned her daughter’s private complaints into courtroom evidence. The two households look nothing alike from the outside, which is exactly what makes it so uncomfortable when their secrets turn out to be the same secret. Coupang Play’s black comedy keeps its tone light even as the blackmail numbers and the body count start to climb.

The Affair Was Just The Beginning Episode 1 — Cheater A EP 01
Cheater A
Jul 31, 2026
Park Kyung-hee has spent years turning a poor upbringing into an influencer empire and a Cheongnam-dong townhouse, so when rumors surface that her actor husband Jae-hong is cheating, she tails him herself rather than wait for the truth. What she finds is worse than infidelity — Jae-hong burying a body, with their daughter Ye-ji somehow at the center of it. The premiere spends its whole runtime demoting an affair to the least of anyone’s problems.

The Affair Was Just The Beginning Episode 2 — The Woman Across The Road EP 02
The Woman Across The Road
Jul 31, 2026
The focus shifts to neighbor Ahn Soo-jung, whose divorce from Bo-sung has curdled into a custody fight built on recordings her own daughter never meant as evidence. A private investigator she hires to dig up dirt on Bo-sung’s lawyer gets struck by a car mid-blackmail attempt — the same accident Jae-hong is hiding. Soo-jung and Jae-hong grow closer while neither wife notices, and both daughters separately confess to being behind the wheel.

The Affair Was Just The Beginning Episode 3 — A Quiet And Secluded Place EP 03
A Quiet And Secluded Place
Aug 7, 2026
With Ye-ji implicated in a hit-and-run, Kyung-hee and Jae-hong stop debating his affair and start debating how far they’ll go to protect their daughter. The two families are already tangled through their daughters’ secret friendship, and that shared burden pushes both sets of parents toward the same ugly conclusion. Jae-hong floats burying the body outright — the moment the cover-up stops being hypothetical and becomes the plan.

The Affair Was Just The Beginning Episode 4 — 99 Million Won EP 04
99 Million Won
Aug 7, 2026
The cover-up buys Kyung-hee and Jae-hong exactly one new problem: a blackmail demand for 99 million won from whoever filmed them disposing of the body. While the parents scramble against the deadline, Ye-ji and Min-seo’s friendship turns out to run deeper than anyone assumed — a kiss, matching rings, a relationship built entirely inside their families’ worst secret. Blackmail turns a cover-up into a countdown.

The Affair Was Just The Beginning Episode 5 — Strictly Business EP 05
Strictly Business
Aug 14, 2026
The affair finally detonates in public at a charity gala, but Kyung-hee leaves with more than confirmation — a second secret Soo-jung’s been hiding. Rattled by police in the neighborhood, Soo-jung panics and hands over the hit-and-run truth without meaning to. Kyung-hee moves fast, claiming she has camera footage that puts both daughters in her hands — then gets deliberately closer to Bo-sung instead, right in front of Jae-hong.

The Affair Was Just The Beginning Episode 6 — The Lawyer Closing In EP 06
The Lawyer Closing In
Aug 21, 2026
Kyung-hee’s world is fraying — a new assignment throws her together with Bo-sung, and his unexpected kindness starts softening her toward the one person she has every reason to resent. Jae-hong’s promises to cut off Soo-jung do nothing at home, and Kyung-hee ends up walking out into the night alone. A lawyer tracing Jae-hong’s car to the hit-and-run starts digging, and Soo-jung — mistaking it for a custody attack — turns to her private investigator, Bo-sung’s own brother.

✍️ KDramaWorlds Editor’s Take

Our real opinion — worth the watch, and for who exactly.

📱 Influencer Meltdown 🤐 Mutual Blackmail 🏘️ Two Families, One Secret 😬 Black Comedy Crime

Park Kyung-hee built an entire brand out of the idea that her life is worth aspiring to, which is exactly why the show keeps its camera on her phone as much as her face — the disaster has to be managed in public as carefully as it’s covered up in private. Kim Hye-soo plays that split without tipping into camp, treating image-maintenance as its own kind of crime-scene cleanup. The genre she’s working in shares more DNA with The World of the Married than with a standard whodunit — infidelity here is the smallest lie in the house, not the biggest one.

The Affair Was Just The Beginning (2026) — cinematic still

The blackmail plot is where the black comedy actually lands, because every character keeps trying to solve a moral problem with a financial one. Ninety-nine million won doesn’t buy anyone’s way out — it just proves the price of silence keeps climbing once you’ve paid it a first time. That’s the same queasy math Mask Girl built its whole back half on, and it works just as well here: a cover-up is never a single decision. It’s a subscription.

Whether the final three episodes stick the landing is still an open question — a show this committed to escalation eventually has to stop escalating and start resolving. What’s already clear is that Kyung-hee’s competence, the thing that built her entire life, is now the same trait digging the hole deeper.

👍👍👍 BEST FOR 👍👍👍
😬 Viewers who want their crime thriller with a genuinely mean sense of humor 🏘️ Fans of dual-family dramas where every secret turns out to be shared property 📱 Anyone curious what an influencer’s crisis-management instincts look like applied to an actual crime

⚖️ Final Verdict
What works
Kim Hye-soo commits fully to Kyung-hee’s pivot from image-obsessed CEO to cover-up mastermind
The blackmail plot escalates episode over episode instead of stalling out
Cho Yeo-jeong and Kim Jae-chul make the second family’s plot feel load-bearing, not a subplot

What to know first
Only 5 of 8 episodes have aired — the final stretch is still unproven
The dark-comedy tone occasionally undercuts scenes reaching for real tension
Episodes release in pairs on Fridays, with the finale set for September 4, 2026

7.3 / 10— A black comedy thriller that’s earned its MDL score so far by making a cover-up feel like a full-time job for two entire families.
