Ruler: Master Of The Mask, the MBC historical drama that is also known as The Emperor: Owner of the Mask, returns with episodes 37 and 38 this Wednesday, July 12, at 10pm KST. These episodes could feature a secret team-up between Crown Prince Lee Sun and the Queen.

The commoner-turned-King might have tried to bribe his legal mother, but she knows that he is not trustworthy. The fake king could betray her once he becomes the real king. So she may decide to help the Crown Prince.

For the male protagonist, it is not enough to claim the throne. Since no one has seen his face, he will have to prove his identity. There are two ways to prove that he is the son of late King Lee Yoon – either by showing the letter of his father or by drinking poison.
