Ruler - Master of the Mask Episode 19

Ga-eun monologs to her father that now she understands why he gives up his life for justice. She decides to go to the palace for the dethroning of the King who is a part of Pyunsoo group. 

Prince says to bring Ga-eun back, but everyone doesn't agree with him. Woo Bo tells him to meet Lee Sun, the King first.

Queen mother asks King if he realizes which part is his, introducing Ga-eun. 

Hwa-gun becomes Dae Pyun Soo, the vice of Phyunsoo group. Her father requests her to have the drug field to operate and receives permission. On the other hand, Dae Mok wonders why Hwa-gun suddenly returns to the group. 

King looks gently at Ga-eun who becomes a court lady to serve him, and Prince sees her on the way to the king, but Ga-eun shakes his hand off. 

Prince is granted to be an audience with King as the head of peddlers. The two of them asked carefully about the current situation in a conversation that only two people would understand. Prince also asked if he saw Ga-eun, but King answered no. 

Ga-eun asks Mae Chang who appears in the court lady's training about the map. Mae Chang was about to answer but didn't because she feels indications of people being around.

Mae Chang asks the King's eunuch if they can help the prince. He answers that the balance among Dae Mok, Queen mother, and Prince is the most important to save their life. 

Ga-eun calls Prince who was leaving the palace in secret and tells him more information about the drug field. Prince however only asks about her. Ga-eun says, "Our relationship is already over," in tears. Prince says, "If you say yes, then I will overturn it." Ga-eun just left without saying anything. 

King learns about their relationship looking at the secene from afar.
