This drama is one of the K-dramas that I watched that I actually finished. I don't finish K-drama's even though its a must watch or very popular. One of the reasons why I like this one is because of Krystal, yes I watched this one because of her. I was finding some dramas of snsd or just some dramas that were made by Krystal or Jessica Jung. Then I found this one on Iflix and I watched it in a very blurry quality but because of her I kept watching then suddenly I just fell in love with the drama itself. It was so good without very nau·seous scenes, some very r18 up scenes, or scenes that are just too much for my weak heart. It was so good, their friendship like the last part where they escape and It's an open ending. I still want for it to have a part 2.
