It is indeed the best drama I have ever watched, and especially the ending I didn't expect it.
Moreover, it teach's such a good lesson and how can one's words change a person's whole life even by knowing them or not and how people shouldn't judge other's on what they see on the internet.
I really recommend everyone to watch it and I can assure that everyone will learn such a valuable lesson from those ten episodes especially kids these days who are always on their phones believing everything on the internet. Anyways watch the drama and you won't regret it.
