Once you hit episode 11, its just outright crazy land.

Especially when the FL is just so bent on revenge, yet truly loved the ML after finding out how much ML had loved her then.

Still she is willing to marry and sleep with the Emperor just to gain power for revenge when she confirms that the Emperor might had a hand in her losing her child and killing her.

I just really cant bent my brain around this story concept, the soul switching was already weird, but this sort of plot just makes it even harder to digest.

Yet at the end ML will still marry FL, crazy.
