Hyeri and Na In-woo have been confirmed as the leads of ENA’s new Monday-Tuesday drama “She Needs Careful Handling” (working title; Korean title 그녀는 취급주의), a fake-marriage action romance that is the Korean remake of the 2017 Japanese drama “Caution, Hazardous Wife,” the production announced on November 12.
The series is written by Kim Ryu-hyun and directed by Yoo Seon-dong, known for “The Uncanny Counter” and “Trigger.” It is scheduled to air in the first half of 2027 on ENA and KT Genie TV.
Hyeri plays Jin Ja-young, an elite spy codenamed “J-Nine” and a disguise specialist who has carried out missions around the world under hundreds of identities. Close to achieving financial independence and early retirement, she is framed and forced into hiding, and begins a new life as a novice housewife living with Gunwoo — a cover she finds harder than any mission. Ja-young believes that the peace of her neighbourhood is her own peace, and has a habit of solving village problems herself before the police can intervene.
Na In-woo plays Gunwoo, a handsome local veterinarian known as a gentle, animal-loving model citizen — with a hidden past as a National Intelligence Service agent. He saves Ja-young by chance, then volunteers to temporarily protect her, and the two begin life as a fake married couple, each hiding their true identity from the other in a “sleeping with the enemy” setup that drives the series’ tension and comedy.
Speaking about the role, Hyeri said she was drawn to Ja-young’s ever-changing nature from the first time she read the script. “Though she is one person, it felt like I could show many sides, as if playing multiple roles in one, and that excites me,” she said, adding that she is working to transform herself into a convincing elite spy. Na In-woo said he was drawn to Gunwoo’s hidden story and reversal — a skilled veterinarian known as a good person with a secret past — and promised to do his best not to be a burden to his senior and fellow actors, asking viewers to look forward to the show’s varied fun and colours.
The role is new territory for Hyeri: it is her first time playing a married woman and her first role as a covert agent since her debut. The casting also marks her return to the small screen as an actress after a busy run as a variety host — she is currently the solo MC of the Disney+ original fashion survival show “Style Wars,” whose first two episodes were released on November 11.
The remake has had a long road to the screen. Reports of a Korean version first surfaced in 2023, when Chae Soo Bin was in talks for the lead role, and the project has since gone through changes in both story and casting. On April 7, 2026, Korean media reported that Hyeri had been offered the role of Jin Ja-young and that Na In-woo had also received an offer for the male lead, with Hyeri’s agency Sublime confirming at the time that it was one of the projects under review. Seven months later, the casting is now official.
Na In-woo, who debuted in 2013, has built his career through hit dramas including “Mr. Queen,” “River Where the Moon Rises” and “Marry My Husband,” and the role of a veterinarian with a secret-agent past gives him another dual-identity lead. For Hyeri, the project follows her ENA romantic comedy “Dream to You” with Hwang In-youp, which premiered on July 13, 2026.
With the leads confirmed and a premiere window set for the first half of 2027, further casting details and a firm premiere date are expected to follow in the coming months.
