so just for the record, this is the synopsis (for those who don't feel like clicking another link):

The reason why its so vague is because it's hard to tell summary without giving anything away. The idea is that there is an undisclosed number of clones that come from one person and were made at the same time. The clones are around high school age at the beginning of the drama. Due to some made-up scifi rules in the world of this drama, although you can physically clone a human, there's only one "life" available for them. For example, let's say there are 10 clones, the 10 clones will all be fighting each other to live because only one of them can fully be alive at a time. There are other things that come up, but that's the main idea behind the story, and kinda explains the "musical chairs" analogy.
I'm not sure if this helped clarify anything, lol. It's a strange drama. I would not suggest this to people who get too caught up in reality. You really have to suspend everything you know and just go with the rules given by the plot.
