He denied it, resisted, and acted as if nothing had happened. It's over. In episode 7 of « Love in Disguise » (known as «Love Undercover» in French), which aired this Monday, Yoon Yi-jun finally admits that he is in love with his secretary and decides to win her over for good. But as the romance heats up, the investigation into Han Eun-young’s murder takes a major turn, with a newcomer holding crucial evidence.
Warning: Spoilers for previous episodes.
The End of Denial
For the past several episodes, Yoon Yi-jun (Yim Si-wan) refused to admit the obvious. After an accidental first kiss, followed by a second, he pretended to be indifferent, all the while constantly circling around Kang Jae-hee (Seol In-ah) and in casually calling her «cute.».
It is his fiancée, Lee Si-ah (Choi Hee-jin), who sets everything in motion. By trying to hire Jae-hee as her own secretary, she sends a jolt through Yi-jun: the fear of losing her finally forces him to acknowledge his feelings.
An Heir Transformed
Once he has made up his mind, the cold-hearted heir undergoes a transformation. The new footage shows him watching Jae-hee intently as she arrives at the mansion, taking care of her, and even offering her the healthy juice he usually saves for himself.
He then goes on the offensive: a reservation at a restaurant with a romantic atmosphere, a flower in his hand. The aloof boss gives way to a man in love, determined to win his secretary’s heart.
Two teasers to make us wait even longer
Two videos released by tvN confirm this change. In the first one, Yi-jun insists on buying Jae-hee a suit, but she flatly refuses to be measured. And for good reason: being measured could reveal that she’s a woman. To make matters worse, Si-ah seems to have hit the nail on the head…

In the second scene, Jae-hee arrives late for work because her bus broke down. Far from getting annoyed, Yi-jun has only one thing on his mind: whether she’s hurt. He tells her not to rush and to get there safely.

Evidence That Changes Everything
But the episode isn't just about romance. In the previous episode, Yi-jun, Jae-hee, and Kim Si-hyun (Kim Jung-hyun), a lawyer with Taegang's legal department, discovered a new clue: a second cell phone belonging to Han Eun-young (Jung Yoo-min), the young woman found dead in a closet. Her last call had been made to Lee Hye-jung, secretary to the chairman of the Taegang Group, played by Yeonwoo.
Yi-jun insists that he did not kill Han Eun-young. But neither he nor Si-hyun knows what really happened on the day of the murder.
A Market Under Pressure
Other new footage shows Lee Hye-jung, fresh from her interrogation, arranging a discreet meeting with Yi-jun, Jae-hee, and Si-hyun. There, she pulls out a pen recorder that belonged to the victim and proposes a deal: she’ll reveal its contents, on the condition that Yi-jun and Si-hyun share what they know about the case.
What is on this recording? And why does the last person to have spoken to the victim have this item? Their true intentions remain unclear.
A consistently strong series
The series is heading into this episode on the back of strong ratings: Episode 6 drew 5.5 % viewers. Below is the full teaser for the episode.
Episode 7 of «Love in Disguise» will air this Monday, November 9, at 8:50 p.m. (Korean time)—12:50 p.m. in France—on tvN and will be available internationally on Prime Video.
