CASENITY.com – tvN is preparing to introduce Love in Disguise, a new Korean drama that combines romantic tension with a murder mystery. The series has attracted attention even before its premiere, particularly because it brings together Yim Si-wan and Seol In-ah as its central pair.

Yim Si-wan takes on the role of Yoon Yi-jun, a privileged heir connected to the powerful Taegang Group. Despite his wealth and status, Yi-jun has a difficult personality and is known for his demanding standards. His situation becomes far more complicated after he finds himself connected to a murder investigation and becomes a suspect in the case.

Meanwhile, Seol In-ah portrays Kang Jae-hee, a former special forces officer who enters Yi-jun's world under an assumed identity. Instead of approaching him openly, she takes a position as his personal secretary, allowing her to investigate the suspicious incident from inside the company.

The unusual setup creates the drama's central conflict. Jae-hee must maintain her disguise while attempting to uncover evidence, whereas Yi-jun has no idea that the person working closely beside him is secretly investigating his connection to the case.

As the investigation develops, professional boundaries begin to blur with personal feelings. The two leads are therefore placed in a situation where trust becomes increasingly difficult, especially when the truth behind the company's secrets could completely change their relationship.

One of the production's biggest talking points has been the transformation of Seol In-ah for her undercover role. Promotional images show the actress adopting a more masculine appearance, including short hair and formal clothing, as she attempts to convincingly portray a woman disguising herself as a man.

The supporting cast also adds another layer to the corporate mystery. Kim Jung-hyun and Yeonwoo are among the performers participating in the project, joining the two leads in a story filled with hidden motives and complicated relationships.

Love in Disguise is adapted from the web novel and webtoon Why Don't You Know She's a Woman? and is directed by Park Dan-hee. The drama is expected to offer viewers a mixture of investigation, workplace intrigue, disguise, and romance rather than following a conventional romantic-comedy formula.

With Yim Si-wan and Seol In-ah sharing the screen for the first time in a drama, their contrasting characters are expected to become one of the production's major attractions. The combination of a suspicious murder case and an undercover heroine gives Love in Disguise plenty of room for unexpected twists as the story unfolds.
