Black Mirror
My heart beats fast when the word "rustle rustle, tadaptap taptap"!! 62 Scary af,. I had to postponed reading it @ night hehehehehehe. the ending and the whole story according to me wanted us to know that world is not what it always seems to be. That people are double faced beasts who are filled with malice, who find happiness by trampling over other's happiness. And if necessary you should be the "taker", which meant that don't let people snatch your true self, don't be naïve to evilness, don't let other people take advantage of your kindness. The true ending is when Taejoon said to Hyunju to "Find a black room when you reach end", from what I see the author wanted to convey was that it is okay to be a evil because doesn't mean that you are a bad person. It is okay to be a little evil and not be a people pleasure, you don't have to fit in society and make them like you. Murder was not the intent of this series.
