Okay so i have very ambivalent feelings towards this drama, because I absolutely love it, but there is something about the drama that makes it a bit dull and boring.

The drama is special from other dramas because of the plot and writing. The plot about elite students being taken hostage by a crazy man is really interesting and I think that the writers and producers did a really good job and how to make the murder mystery work. The drama is short which makes it much more approachable for the viewer to start the drama.
What is worth noting is that the cast is absolutely amazing! So many famous actors today are in the drama and it is so interesting to see them so young. The group of students are what makes the drama so great. They are an interesting group of different types and all of them gives something to the story.
I would definitely recommend this drama! The drama is a bit slower and on the older side, but it is a real gem!
