This is my 1st review even though I've watched around 100 kdramas. Its just that i am that much hyped after finishing this. so whether you should watch this or not? I'd recommend it 100% but still few key points for you guys to decide whether to watch it or not
• If you're a fan of either main leads then absolutely watch it you'll not be disappointed.
• If you're Action/Mystery fan the this is for you. There are tons of action scenes and the mystery behind PSJ & the plans of evil camp will keep you hooked
• You want something refreshing apart from generic kdrama

I don't know how to list more but just watch it. Of course finish season 1 first & I liked season 2(9.0) better than season 1(8.5).

Happy watching ✌️
