Ruler: Master of the Mask Episode 11

Prince heard the news that Yangsu-cheng is collecting all their loans while practicing his martial arts. He is curious about Dae Mok's move. He decides to check what Pyunsoo group is collecting in secret. 

Prince and Chong-woon sneaked into Pyunsoo's secret place. They figure Pyunsoo group is collecting Copper. 

Prince hears a noise and sees Ga-eun with two men caught by Pyunsoo's guards. Tae-ho recognizes Ga-eun and wants to kill her, but the prince rescued them. 

Prince flees with her on a horse. Ga-eun sees his face and is surprised. She calls the prince Chun-soo, but the prince denied. 

The prince at peddler's meeting says to stop using currency but use other materials in markets for a while. He asks the group about copper circulation. Nobody knows in detail except most of it is imported from Japan. 

Ga-eun arrives at the place of peddlers. She finds the head and is surprised once again. The prince tells her he is not Chun-soo who she is looking for but still brings her in to ask the reason she visited his place, looking at her bloody foot. 

At night, Prince confesses Chong-woon that he feels sorry for himself for not revealing his identity to Ga-eun. But at the same time, he feels relieved that Ga-eun doesn't know he is the crown prince who drove her father to tragic death. 

The mother of King concerns that King accepts everything Dae Mok requests. But one day, King Lee Sun sees one request to execute his subjects who damage the Yangsu-cheong wall. He recalls his father's death and order to release people who were caught by Yangsu-cheng rather than execute them. 

King is, however, poisoned by Pyunsoo group and has to take the poison regularly to maintain his life. He goes to see Dae Mok to receive the poison. Dae Mok warns the king to ever be against to Pyunsoo group again. 

Hwa-gun becomes the head of big merchant group and runs her business in Japanese trade. 

The King tries to suicide after leaving Dae Mok's place but is stopped by a man. He wants to express his gratitude to King for the grace to save his father's life. 

Prince arrives in the capital. Ga-eun asks again why he comes here to see wealthy merchants rather than going to poor village to save lowly people. The prince tells her how he solves the problem.

Hwa-gun is leading the meeting. She speaks that even if they could pay everything back to Yangsu-cheong, stop dealing with Yangsu's money to prevent further issues. 

The prince enters into the meeting raising a question of the current money crisis caused by Yangsu-cheong. Hwa-gun recognizes the prince.
