By concept I meat the idea behind having a school on an island (in this case Jeju), catered towards the elite. Have seen several dramas like this but the students were either teens or university students. I don't think casting little kids in this type of elitist environment is healthy for viewers.

The children, at a very young age, already act as brats and feel that just because they have the money, they can act poorly towards others. This was such a turn off.

The drama started interestingly enough but after 2 to 3 episodes, flaws were everywhere. Felt like the characters were just going with the flow of the script without wondering why the writer wrote the story that way. I am just watching it when I have spare time from the current dramas airing recently so I am still at ep 9 (despite having started almost 2 weeks ago).
