K‑drama Love in Disguise dated late 2026

A new tvN drama just moved from rumor territory into something more concrete. “Love in Disguise” got its first official stills on May 7, 2026, which matters because this is usually the point where an “upcoming” K-drama starts looking real, not just cast-on-paper real. The show pairs Yim Si-wan with Seol In-ah, and the hook is not a soft office romance. It’s a thriller-romance built around a murder accusation, an undercover secretary, and a chaebol heir who may or may not be exactly what he seems. (soompi.com) ### What is this drama actually about? The premise is cleaner and stranger than the English title makes it sound. Yim Si-wan plays Yoon Yi-jun, a third-generation chaebol successor who becomes a murder suspect. Seol In-ah plays Kang Jae-hee, described in current listings as a for(soompi.com)stay close to the man she’s investigating. (soompi.com) ### Why are people talking about it now? Because the first stills are usually the first visual proof of tone. They show Yim Si-wan in full polished-chaebol mode and Seol In-ah in the secretary role that hides the undercover setup. That doesn’t sound huge if you don’t follow K-dramas, but this is the stage when distributors, fan communities, and drama trackers start treating a series as part of the active release pipeline. (soompi.com) ### Is the late-2026 date real? Real-ish, but not fully locked in by the network in the way a final press release would lock it. What’s solid is that tvN is attached and the show is listed for 2026 across major drama databases. MyDramaList currently shows an October 26, 2026 star(soompi.com)ble, and “official final schedule” is still a step away. (mydramalist.com) ### What’s the Korean title telling us? This is one of those cases where the local title gives the vibe better than the English one. Listings tie the drama to “나의 유죄인간,” which gets rendered in English as “My Guilty Human,” while older source-material titles include versions of “Why Don’t You Know It’s a Girl?” That mismatch tells you the adaptation may be leaning harder into mystery and identity-play than a straightforward rom-com would. (mydramalist.com) ### Is it based on something? Yes — current databases connect it to a Kakao Page web novel and webtoon. That matters because adaptation fandom is its own machine. If a drama has existing source material, viewers start comparing casting, tone, and plot emphasis early, long before episode 1 airs. It also helps explain why the concept feels a little busier than a standa(mydramalist.com)l. (en.everybodywiki.com) ### Why does the cast matter? Yim Si-wan is the big stabilizer here. He tends to get cast in projects that need someone who can play controlled, ambiguous, and quietly intense without tipping into melodrama. Seol In-ah gives the show a different kind of energy — warmer on the surface, but believable in a role that needs competence and cover-story charm at the sa(en.everybodywiki.com)niche gamble and more like a serious tvN package. (mydramalist.com) ### So what should viewers take from this? The main update is simple: “Love in Disguise” is no longer just a social-media rumor about a someday drama. It now has official stills, a defined network home, a clearer plot pitch, and a believable late-2026 runway. The exact premiere date may still move, but the show itself looks firmly in motion.
