In the 13th episode of Rooftop Prince that aired on May 3, Park Ha (played by Han Ji Min) and Hong Se Na (played by Jung Yumi)’s real mother Mrs. Jang (played by Na Young Hee) appeared again. Accordingly, it’s tipped that the fact that Park Ha and Hong Se Na are sisters will soon be revealed. It’s important because it implies their relationship in the Joseon Dynasty period and the present.
At the end of the episode, prince Lee Gak (played by JYJ’s Yoo Chun) realized how Park Ha and the crown princess were related. As he started to solve the mystery, it will now be the main story of the series towards the end.
The producer Ahn Gil Ho says, “The first part of this series was about how the prince and his men would get used to modern times, the middle part was about the prince and Park Ha falling in love. The last part will mainly be about how they will solve the mystery about the murder case of the crown princess.”
Ahn also says, “As the prince tries to solve the mystery, you’ll be able to see the strong plot of the series.”
