Joo Won tears up after learning about his father's real identity.

In the 15th episode of the MBC drama "Level 7 Civil Servant" that aired March 13 featured Han Kil Ro (Joo Won) and Kim Seo Won (Choi Kang Hee) shedding tears because of Han Kil Ro's father Han Joo Man (Dok Go Young Jae).

Han Kil Ro agrees to accept the fact that Kim Seo Won has to keep investigating his father, Han Joo Man after learning about her true intentions. Han Kil Ro hands over his father's confidential documents and says, "If my father is a bad person, please forgive him."

Han Kil Ro goes home and tells Han Joo Man, "Father. Who is John J?" and hands him Choi Woo Hyuk's photograph. He asks again, "Do you know him?" Han Joo Man answers, "How do you know him? Who did you meet that gave you this?"

Hang Kil Ro asks again, "Who is Choi Yong Soo? I'll tell you everything if you just answer me" and Han Joo Man says, "I didn't do anything wrong. It was a normal deal. All I did was deposit the money into his account after hearing that it was his father's account." John J and Choi Yong Soo were father and son.

Han Kil Ro tells his father, "I'm a secret agent for the national security. Your son is currently working as a national intelligence service agent. Father, are you a bad person?" However, Han Joo Man only says, "You can't even earn much by working for the national intelligence service."

Han Kil Ro returns to Kim Seo Won and says, "It's okay. My dad really cares about money. He would do anything for money so it's not surprising. It's so obvious, I knew it" and begins to cry after suddenly realizing everything. Kim Seo Won hugs Han Kil Ro and begins to cry after saying, "I'm sorry, I'm so sorry."
