Hyeri and Na In-woo Eye Caution, Hazardous Wife Remake

Hyeri and Na In-woo are in talks to lead the Korean remake of Caution, Hazardous Wife, with MyDaily reporting on April 7 that Hyeri had been offered protagonist Jin Ja Young and OSEN reporting the same day that Na In-woo had received the male lead offer. Hyeri’s agency said the project was one of several dramas under review, while Na In-woo’s side had not issued a matching statement when the reports landed. The remake adapts the 2017 Japanese series of the same name into a Korean spy-marriage thriller, and that premise alone gives this development story more bite than a routine casting leak. ENA has not announced a release window or production timetable yet, which keeps the project firmly in the offer stage for now. According to the April 7 casting reports, the upside is obvious if both deals close. The series would pair one of K-drama’s sharpest reinvention stories with an actor who still feels underused in material that demands tension and scale.

Hyeri is reportedly up for Jin Ja Young in the remake

Hyeri has reportedly been offered Jin Ja Young, a woman who enters marriage as part of her cover and starts policing her neighborhood before the authorities can step in. MyDaily’s April 7 report said the Korean adaptation keeps the core setup of a spy wife in hiding living with a husband who is also concealing his true identity. That pitch is pulpy in the best way, but it also sounds built for Hyeri’s current lane. After darker, sharper work and her continued run of high-visibility drama casting, she has the credibility to sell a lead who needs charm, suspicion, and sudden violence in the same performance. We have already seen HITKULTR readers respond to her next-project momentum in our coverage of Dream to You, another recent ENA casting story, and this role would push her image in a much riskier direction.

Na In-woo would bring weight to the husband role

Na In-woo is reportedly in talks to play Jin Ja Young’s husband, a National Intelligence Service black ops agent who is hiding his identity under the same roof, according to OSEN’s April 7 casting report. That dynamic matters because the remake only works if the male lead can play romance, suspicion, and tactical menace without flattening the tone into straight melodrama. Na In-woo has the screen presence for that balance, and the role sounds more layered than the kind of earnest nice-guy parts that have followed him in recent years. The Korean version also appears to be positioning the marriage itself as the main battlefield, as reported by Korean casting coverage on April 7, which should give the drama a cleaner hook for global viewers than a standard espionage procedural. If the final script leans into psychological chemistry instead of pure action, this pairing could land harder than people expect.

The remake angle gives the project an easy international hook

Caution, Hazardous Wife is based on a 2017 Japanese drama, and that remake label instantly gives the Korean version a built-in comparison game for international viewers. According to the April 7 Korean casting reports, the story follows a spy wife in hiding and her husband, a black ops agent from the National Intelligence Service, with both characters concealing their real motives while living together. That is a clean elevator pitch, and it is easy to see why Korean producers would revisit it now, when sleek thriller-romance hybrids travel well across streaming audiences. There is also a wider K-drama conversation here about how aggressively the industry is mining proven IP, something English-language fan spaces and podcasts like Play on K have spent years dissecting from a viewer-first angle. If the adaptation sharpens the stakes instead of simply localizing the original, the remake discourse could work in its favor.

What happens next with the Korean remake

Nothing is locked yet, and that is the most important caveat in this story. Hyeri’s agency only said the drama is under review, and Na In-woo’s side had not issued a formal response when the reports surfaced. The project also carries some development history, because earlier remake chatter dates back to 2023 and the package appears to have changed since then. That makes the next official casting statement more meaningful than the usual rumor-cycle follow-up. According to Hyeri’s agency statement carried by MyDaily, the project remains one of several scripts under review, so the next hard update still needs to come from the production side. If both actors confirm, the conversation will quickly shift from whether the remake is happening to whether the production can turn a strong concept into one of 2026’s must-watch thrillers. Right now, the casting alone feels smart. The harder part will be translating a recognizable Japanese setup into something that feels unmistakably Korean rather than just efficiently repackaged.
