The Affair Was Just The Beginning
📋 Drama Overview
What to expect, before you press play.
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.

✍️ KDramaWorlds Editor’s Take
Our real opinion — worth the watch, and for who exactly.
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 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.
