Story:
As a psychological thriller lover, this was totally my type. I was on the edge of my seat throughout the whole journey and often forgot to eat while binging. Not to mention it was enough to make me lose my sleep those 2 days.

Acting:
10/10 Can you expect anything less from LEE DONGWOOK & IM SIWAN?? They're both legendary and so versatile. Apart from the the other actors were incredible too. Their perfect acting made me lose my mind abs question my existence for the time being.

Rewatch value:
I usually don't rewatch anything. My watchlist is too long. So probably not.

Overall:
It may not be your liking if you're not familiar with this genre. It may seem a little boring to you if you're used to too much melodramatic stuffs. But trust me psychological horror lovers this will blow your mind. I'm very much satisfied with the open ending. You can interpret it however you want. This is my ultimate favorite thriller drama.
