It is the 7th year of the non-marriage law. Heon hears the rumor that the King is impotent and goes undercover with Shin-won. So-rang gets caught red-handed and changes suddenly.
So-rang tells Heon to go out and find the source of the ghost sound that bothers him. When they reach the pond, something flashes through So-rang's mind.
Heon gets shocked again by looking at Mr. Ahn in the palace. So-rang is taken somewhere by the conspiracy of the group named Byung-pan. Where is she now?
So-rang rejects Heon after he confused her and the crown princess. Heon goes out of the palace to win her heart, but there is someone who is targetting him.
Hwa-yoon, Hyeon-hee, and So-rang enter the room for re-selection of a spouse for the King. All of a sudden, one of the young ladies has blisters all over her face. So-rang is suspected of being behind it.
