Love In Disguise Episode 1 recap: Yi-Joon and Jae-Hee's contrasting personalities

Episode 1 starts with Yi-Joon leaving the plane as the reporters wait for him. He is the youngest member of the economic delegation and is stated to be the successor to the chairman of Taegang Group.
From what I saw in the episode, it feels like Yi-Joon doesn't care much about others and seems to be a bit self-obsessed from the way he cares about his photos and his personality.
Jae-Hee, on the other hand, is seen saving a girl when a can suddenly bursts in a store. She looks brave, someone who likes helping others and has great fighting skills.
Love In Disguise Episode 1 recap: Yi-Joon put under suspicion after a murder

In Love in Disguise, Han Eun-young, the secretary for Taegang Group, dies after being strangled to death with a belt. As the authorities investigate the case, they find Yi-Joon's fingerprints on the body and belt. Jae-Hee also starts her investigation into the case and speculates that the perpetrator is left-handed or ambidextrous.
When Yi-Joon is called for questioning, he gives the silent treatment most of the time. When asked about the relationship rumors between him and the secretary who died, he asks in return whether she had a crush on him.
In the end, Yi-Joon leaves the questioning without giving the investigators much to work with and tells them to solve the case themselves. The higher-ups also want the special unit to stay away from him because of his powerful background, making it harder for Jae-Hee and her team to investigate him freely.
Jae-Hee later receives a draft with a note reading that Yi-Joon killed her. It also contained a pendrive that had the video of Yi-Joon having an argument with the secretary. They also learn that the secretary was using two cellphones.
Love In Disguise Episode 1 recap: Jae-Hee goes undercover to investigate Yi-Joon
Towards the end of Episode 1, as I watched the episode, I found Jae-Hee coming up with a new solution. She finds a job posting for the secretary at the Taegang Group and decides to apply for the role so she can investigate Yi-Joon closely. The only problem is that the posting was open only to male applicants. But she says that she has been mistaken for a man because of her appearance and style, and she will still apply.
She goes for the interview, where Yi-Joon asks her a few questions, including whether she has killed anyone, which leaves her shocked. She says that she witnessed the murder of a senior. After being rejected, she saves Yi-Joon from a few people to try to be on his good side, which leads to her getting hired.
The episode ends with Jae-Hee reaching Yi-Joon's residence with a camera on her glasses to investigate him without being caught. But he takes off her glasses, saying her cover is blown.
