Plan is in.

I guess it is really just the four gals' plan, and not Sang Mi's. This time the episode focuses on how the cult works. It is not bad to believe in spiritual being, but not to the point of neglect. The message Sang Mi wanted the believers to realize that they have been used by Guseonwon. Bit look how they easily disregarded Sang Mi and even accused her of being possessed. It happens in the real world, those who are master in manipulating people, they could easily brainwash their followers and get whatever they want.
