Duty vs. Desire: Yim Si-wan and Seorina Star in Prime Video’s ‘Love in Disguise’

Adapted from the hit web novel Why Don’t You Know It’s a Girl?, the highly anticipated series is set to launch exclusively on Prime Video in the Philippines and over 240 countries and territories worldwide on October 19.

Prime Video has officially announced that Love in Disguise, a highly anticipated Korean series blending romance, comedy, and suspense, will make its exclusive global debut on October 19. Streaming in over 240 countries and territories, the drama pairs Yim Si-wan and Seorina in a high-stakes game of deception and desire where a dangerous investigation forces them to choose between duty and love.

Adapted from the hit Kakao Webtoon Why Don’t You Know It’s a Girl?—which has racked up over 8.15 million views—the story centers on Kang Jae-hee, a former special forces officer who now works as a police detective. Assigned to investigate and protect Yoon Yi-jun, a cold-blooded conglomerate heir suspected of murder, Jae-hee goes undercover as a man to infiltrate his security detail. However, when her secret is exposed, both characters must navigate a dangerous web of vulnerability, betrayal, and unexpected love.

Fresh off his roles in Squid Game Seasons 2 and 3, Run On, and Strangers from Hell, Yim Si-wan stars as Yoon Yi-jun, a cynical third-generation conglomerate heir. Hardened by family politics, Yi-jun trusts no one—until he is named a murder suspect and hires Kang Jae-hee as his personal bodyguard. Jae-hee’s loyalty cracks his cold exterior, sparking an intense attraction that leaves Yi-jun questioning his own identity as he falls for his seemingly male protector, leading up to the shocking discovery of her true gender.

Stepping into the role of Kang Jae-hee is Seorina (Business Proposal, Twinkling Watermelon), a fierce ex-special forces operative turned rising star detective. Jae-hee’s professional demeanor and sharp looks are so disarming that women constantly mistake her for a handsome man. When her superiors tell her to back off a murder case tied to wealthy heir Yoon Yi-jun, her stubborn streak kicks in. Posing as a man, she successfully lands a job as Yi-jun’s personal bodyguard—giving her the perfect cover to cater to his schedule by day and hunt for clues by night.

Jointly produced by CJ ENM STUDIOS and PITAPAT STUDIO, Love in Disguise delivers a gripping mix of secret identities, high-stakes investigations, and accidental romance. The highly anticipated drama launches on October 19 exclusively on Prime Video in Thailand and over 240 countries and territories, with new episodes rolling out on a weekly basis.
