The drama was haotic at many points, the acting was debatable to say the least, but overall I liked it. The drama was interesting and I was curious about all the characters and their fates.
Music did not play a big role in the drama. At least that was my impression. Many scenes took place with the same melodic note. There were very few songs, more instrumental pieces.
For Korean realities, I think that the drama touched on a controversial topic: ubiquitous sponsorship, i.e. prostitution among famous people.
I would like to watch a similar drama about the double lives of stars with a better scenario. Such stars who sell their body in exchange for fame. Without the embellished reality and naivety that are often in dramas. But it's probably only Netflix that would go for such an honest project. There was a lot of truth here, I suppose, but nonetheless, I think more could have been shown on this topic.
