"Level 7 Civil Servant" Joo Won and Choi Kang Hee are caught living together by her parents.

March 21, the 18th episode of the MBC drama "Level 7 Civil Servant" featured Han Kil Ro (Joo Won) and Kim Seo Won (Choi Kang Hee) getting caught living together by her parents.

While Hang Kil Ro and Kim Seo Won are hugging, her parents Kim Pan Suk (Lee Han Wee) and Oh Mak Nae (Kim Mi Kyung) enter the house. Kim Pan Suk asks, "You're visiting again?" and Han Kil Ro replies, "Hi, you're here!"

Oh Mak Nae then says, "Were you guys wrestling just now? You guys are like this every time we come. Did you move in or something?" Right then, Oh Mak Nae sees Han Kil Ro's underwear hanging to dry. Oh Mak Nae panics and asks, "What have you done to our Kyung Ja? Did you go as far as you could?" and begins to demand answers.

Han Kil Ro answers, "We didn't go as far as we could go."

Oh Mak Nae adds, "After all the times I told you to be careful. How are you going to take responsibility for your actions? Answer me right now." Kim Seo Won says, "It's not like that. He came to work." Oh Mak Nae says, "This late? What work? I'm going to go crazy."

Ironically, Han Kil Ro's mom visits right then and meet Kim Seo Won's mom for the first time. The mothers attempt to decide what they will do with their children.
