I literally just finished this drama today and I have to say, it’s REALLY good! It was recommended to me on Viki and after reading the synopsis, I was intrigued. I actually ended up watching most of the episodes in one day. Luckily for me, all except the last two episodes were already available. I loved the casting and the acting was AMAZING. There was a big plot twist that definitely caught me by surprise. Usually I can predict what’s gonna happen in these dramas but I was pleasantly surprised this time around! I definitely recommend this if you like apocalyptic/thriller/slightly dark dramas. Ah! It was just so good! I haven’t watched a kdrama all the way through in a WHILE.
