On the 15th episode of KBS 2TV Wednesday/Thursday "Joseon Shooter" broadcast on August 13th, Jung Soo In understood that Kim Ho Kyung (played by Han Joo Wan) was the cabinet member's son.
Soo In went to the court to meet the queen and saw an unexpected seen. This was the son who was trying to get on the good side of the guard. However, he hears that the guard is Kim Byung Je's son and that he was shaking his tail. This story went back to Soo In right away.
Soo In was in shock hearing that Kim Byung Je's son was actually the person that killed his father and was in shock. She said to Ho Kyung, "what are you talking about? You're the son of the cabinet member. Is that true?" and kept repeating that.
At this, Ho Kyung didn't have anywhere else to go back to and said, "Yeah, my father is the cabinet member. I should've said earlier but I'm sorry I hid this" and told the truth.
Meanwhile, "The Joseon Shooter" is a romance action drama about Park Yoon Kang becoming a shooter. It features Yoo Oh Sung, Lee Joon Ki, Nam Sang Mi, Jun Hye Bin, and Han Joo Wan.
