Joo Won gets curious about who keeps contacting his girlfriend Choi Kang Hee and asks for her password.

During the 16th episode of the MBC drama "Level 7 Civil Servant" that aired March 14, Seo Won's (Choi Kang Hee) phone keeps ringing while she is on a date with Kil Ro (Joo Won).

When Seo Won's phone keeps ringing, Kil Ro asks, "Mother? Father? Your brother?" trying to act like it's not bothering her.

Seo Won replies, "It's a text about a credit card I just signed up for." Kil Ro gets suspicious and adds, "It kept coming. You can just tell me who they're from." Kil Ro eventually gets upset from jealousy and says, "Let's tell each other our passwords" and naturally tells Seo Won his password.

However, Seo Won is unhappy and just says, "Why do you want my password?" and Kil Ro replies, "I'm not going to touch your personal life and I'm not even going to ask for your password. But who are the texts from?" Seo Won replies, "I like interest but not possessiveness."

Kil Ro was worried about various things. He was concerned about his father's confidential documents that he showed her. Even though they had the same job description and worked together, there were a lot more things they had to be careful about.
