Actress Seol In Ah is showing a different side of herself in tvN's new drama Love in Disguise, drawing attention for her impressive action skills and dramatic transformation into a tough detective.

The drama, which premiered on October 19, features Seol In Ah as Kang Jae Hee, a former special forces member turned detective who goes undercover to investigate a murder case involving a wealthy businessman.

Unlike her previous roles, Seol In Ah takes on physically demanding action scenes while portraying a character who relies on quick thinking, strength, and determination.

Her character disguises herself as a man to work as the personal secretary of Yoon Lee Joon, played by Im Si Wan, a third-generation chaebol heir suspected of murder.

Through her sharp movements, powerful fighting scenes, and confident expressions, Seol In Ah brings out the character's strong personality and professional background.

Her action performance had already received praise from director Park Dan Hee even before the drama premiered.

During the production press conference on October 14, Park expressed admiration for the actress's physical abilities, saying, "I've never seen an actress who performs action better than the action team."

The director's remarks have gained renewed attention following the broadcast, with Seol In Ah demonstrating the action skills highlighted during the event.

Beyond the fighting scenes, the actress also underwent a major visual transformation for the role.

She adopted a short hairstyle and adjusted her walking style, posture, and body movements to convincingly portray a female detective hiding her identity as a male personal secretary.

Her agency, Gold Medalist, highlighted the effort she put into preparing for the character.

The agency explained, "Seol In Ah's bold transformation through her male disguise has also brought out a different charm."

It added that she carefully worked on small physical details, including her posture and center of gravity, to make the character's disguise more convincing.

Gold Medalist also encouraged viewers to support the actress as she moves between the character's true identity as a detective and her undercover role.

Seol In Ah previously appeared in popular dramas such as Business Proposal, Oasis, and Twinkling Watermelon, where she showcased her charm through romantic, emotional, and youthful characters.

With Love in Disguise, she is expanding her acting range by taking on intense action scenes and a challenging undercover role.

As the drama continues, attention is now on how Seol In Ah will further showcase her action abilities and bring more depth to her character.
