This story is getting interesting. First with the duchess (I don't know how people can identify others with something like the way they walk or in this case how she plays the violin, but we don't know if she is actually the princess to confirm that to be right) and how she realizes that the princess is a fake, and another kiss scene with her and the commander, and Felix having sex with this fake and arrogant princess just to confirm that she is not his sister. Like this story has really turned upside-down in the last few chapters.
