A tense and addictive romance thriller is on the way, bringing together Im Si-wan and Seol In-ah (Seorina) in a high-stakes, dopamine-fueled pairing.
tvN’s upcoming drama ‘My Guilty Human’, set to premiere in 2026, tells the story of an arrogant third-generation chaebol who becomes the prime suspect in a murder case, and a former special forces officer who secretly infiltrates his life as his personal secretary. The series is written by Moon Soo-jung and directed by Park Dan-hee, with production led by CJ ENM Studios and PitaPat Studio.
Known for his ability to fully immerse himself in complex characters, Im Si-wan takes on the role of Yoon Yi-joon, the next-in-line heir of the nation’s top conglomerate, Taegang Group. On the surface, Yi-joon has everything — looks, intelligence, and power — but his extreme sensitivity and obsession with perfection make him notoriously difficult to work with. After a murder occurs within the company and suspicion falls on him, Yi-joon withdraws from the public eye, only to re-emerge after hiring a new personal secretary, setting off a dramatic turning point in his life.
Seol In-ah plays Kang Jae-hee, a highly trained police officer with a special forces background. Skilled in combat and tactics, Jae-hee disguises herself as a male secretary to get close to Yi-joon and uncover the truth behind the murder case. As she navigates her dangerous undercover mission, she finds herself trapped in an unpredictable daily routine under a demanding and volatile boss.
The relationship between Yi-joon and Jae-hee is built on layered tension. One is a murder suspect hiding behind wealth and power, while the other is a detective tasked with exposing him — all while posing as his closest aide. As they spend more time together, their dynamic evolves into a complex mix of suspicion, protection, emotional push-and-pull, and unexpected attraction, blurring the line between romance and rivalry.
‘My Guilty Human’ is based on the popular KakaoPage web novel and webtoon ‘Why Doesn’t He Know I’m a Woman?’, promising a unique blend of romantic comedy, psychological tension, and thrilling investigation. Alongside the central mystery, the drama will also explore the chaotic teamwork of detectives racing to uncover the truth behind the murder.
With its combination of romance, suspense, and dark humor, ‘My Guilty Human’ is shaping up to be one of tvN’s most anticipated dramas of 2026. Fans are already looking forward to seeing the intense chemistry between Im Si-wan and Seol In-ah as their characters collide in a dangerous game of trust and deception.
