What are the grounded plots in the Korean drama "Druna Hotel"?

"Druna Hotel" is a deep Korean drama with many grounded plots. Here are some I found:

1. Each character in the play has his own story, his own past and future. The stories of these characters are very real and touching, which makes it easy for the audience to sing.

There are many themes about love, friendship and family in the play. These themes are grounded and easy for the audience to understand and accept.

There are many questions about human nature and society in the play. These questions are profound and meaningful, so that the audience can think about life while enjoying the plot.
