Actors Im Si Wan (Siwan) and Seol In Ah are set to showcase their on-screen chemistry in a new comic yet suspense-filled romance drama.

On December 18, tvN officially announced the lead cast for its upcoming drama ‘My Guilty Man’, written by Moon Soo Jung and directed by Park Dan Hee. Im Si Wan and Seol In Ah have been confirmed as the main leads.

‘My Guilty Man’ is a close-quarters thriller romance adapted from the popular KakaoPage web novel and webtoon 'Why don’t you know I’m a woman?.' The story centers on an unusual alliance and confrontation between Yoon Yi Jun, the third-generation heir of Korea’s top conglomerate, and Kang Jae Hee, a former special forces police officer.

The drama follows a chaebol heir who becomes a murder suspect and a detective who disguises herself as his male personal secretary to uncover the truth. Blending romance, suspense, and chaotic teamwork between police officers, the series promises a wide range of engaging episodes.

Im Si Wan takes on the role of Yoon Yi Jun, the next successor of the Taegang Group, Korea’s top-ranked conglomerate. While he possesses both striking looks and exceptional ability, he is also an extremely sensitive perfectionist. Known for his versatility across genres, Im Si Wan is expected to once again deliver a finely tuned performance that adds both tension and anticipation to his character’s journey.

Seol In Ah stars as detective Kang Jae Hee, a highly skilled officer with expertise in various martial arts and a background in special forces. Determined to uncover Yoon Yi Jun’s true nature, she goes undercover as his male aide. Seol In Ah is set to bring lively charm to the role, portraying Kang Jae Hee’s unpredictable daily life alongside her temperamental boss with warmth and humor.

Together, the two actors will depict a subtle dynamic that exists somewhere between romance and bromance. As they spend more time together, their relationship deepens, evolving into a sweet yet tense psychological battle.

‘My Guilty Man’ is scheduled to premiere next year on tvN.
