After finally watching this, I understand why it is consideres a "must see"/classic.
So many other C- and K-dramas have obviously been influenced by this.
If anything, I recommend watching this as an insight into this type of dramas.

I happened to watch the Chinese adaption (Meteor garden) of this before this Korean version. Not sure which one I like the most, to be honest.

Even though the script had some questionable logic here and there, the story itself contains "it all": rich and poor, love rivalry, disapproving parents ...
