The film's final scene takes place in the king's bedroom. The king is convinced that he now has both Ja-Oak's heart and body. The audience is still unsure, adding a subtle air of violent tension to the scene. A wild, languid lovemaking montage cuts between extreme close-up's of their passionate bodies, sexually perspiring faces, with a single superimposed flame marking the center foreground of the image. Repetitive piano notes, heard in all the sex scenes, drone onward.
Passion turns to violence.
Ja-Oak pulls a tiny silver dagger out of her mouth and slowly works it to the king's nape. Ja-Oak achieves poetic vengeance by inserting the dagger into the king's nape at the point of sexual climax, and then committing suicide. A voice-over provides the film's epilogue. Even with Ja-Oak's revenge and the master eunuchs brave mutiny, Eunuch paints a grim, pessimistic view of life within the royal palace. Sang-Ok's treatment of this similar theme is more liberating in the final story of Choson Dynasty .
