I never expected this much from a K-Drama. This is sure to be an amazing masterpiece. Nothing is predictable. It gives "Parasite" + "Adamas" vibes, still pretty much unsure how it's going to end.
I just started watching this series & just watched 2 episodes. Everything feels like perfectly made. To be honest, I get the vibes of "Adamas". Frankly speaking this isn't an adaptation of "Little Women" by Louisa May Alcott, rather than it's just an inspiration. That blue-orchid feels like killers' signature.
N.B. - I'm talking about paid official streaming services; not those cheap dramacool & piracy sites.
