I would say after watching the entire show that this drama really made sense to me.
Every character had their own story and struggle and instead of clear demonstrating them black or white (pure good or pure evil) this really showed them Grey
Good had their share of bad and bad had their share of good qualities which was the key point I personally really enjoyed.
No one was solely"Hero" or "Villian" every one was "Character"

Long story short ?
I really enjoyed the show it was fun watching it.
I would definitely recommend
U SHOULD DEFINITELY WATCH THIS.
