[Moonlight Drawn by Clouds - ep 7]
In this scene, Eunuch Ma Jong Ja was confessing his love for palace lady, Wol Hee through a puppet show.
At first, Wol Hee got angry when she realized the puppet show was about those two. She thought they were mocking her for getting mad at Ma Jong Ja for not being able to claim that he loves her in front of everybody.
(All palace/court ladies are meant for the king so they were secretly in love. Eunuch Ma could not say he loved her directly, in front of everyone so he did it through a puppet show.)
