I added this drama to my list about a year ago or so solely because Park Boyoung, if she's in it I'll watch, literally anything no matter what it is or what it's about. I knew this was based on a manhwa by the same author of Moving, another 10/10 series, and I planned to read tje source material, but I never did.

I came into it confused, not really knowing what was going on, scared and anxious, pretty much like one of the characters in the series. Every thing about this series is absolutely perfect, the dialogue, lighting, sounds, ambience and the subtle foreshadowing kept my eyes glued to the screen the entire time.

My advice, watch with as little information about it as possible, pay close attention every single detail is important.

There's a post-credit scene in the final episode, be sure to watch. It's awesome!!
