The core and motor of the series is certainly the horrific experience of the ML, potentiated by the despicable brother and the irresponsible, evil mother. The associated psychological deformation of the ML then continues to determine the plot. The FL also has a difficult fate with the family she has to feed.

I can't understand the brother's sparing after this terrible deed is solved. Perhaps it is due to the authors' need for harmony. I would have wished him a few dozen strokes of the cane and eternal banishment, together with the evil mother who multiplied the misery of the poor boy Joung Yoon. Up to the forced renunciation of his own identity!

Overall, though, a successful construction of a dark mystery.

Other than that, I mainly found the series very entertaining and funny, especially the office mates and their entanglements. All very amusing, as is the love story of Mi So and Young Joon.

Ms. Park Min Young is pretty and sexy, Park Seo Joon is good looking, all nice!
