I am in episode 10 haven't finished it but know how it will end. I still think mercy for none is much better. I'd rate this a 7.5/10. Mercy for None was near perfect for me.
I REALLY love this drama and I am just in episode 4! It's much better than cashero and has the same serious vibe as Moving, especially with the villains.
Sincerely,
Kdrama fans.
