Currently 3 episodes in and I'm hooked. The acting is great. Ever since "Train to Busan" I've kept up with Gong Yoo's career and this so far is another winner. The music creates an immersive experience and the tension, fantastic! It's a slow burn but so far an amazing slow burn. I don't know where's it's gonna go or how it's gonna end but up this point I highly recommend it.
