It's hard to stop watching once you get into it. The story could get a bit confusing at time but with a bit if patience they explained it very well. The actors were extremely good at conveying emotions and Song Kang may be a rookie but he made it so easy to fall in love with him that you couldn't help but smile when he did.

I really hope Netflix won't dog as they have with most poc series they have with this one because the ending was so far from complete being only 8 episodes. I really hope people watch it because nothing about it predictable or familiar in the way most k-drama are after a while. Like you can't genuinely tell at all where they are taking this. How they use technology in this series is very Black Mirror in the best way whole maintinug a very real slice of life feel. I never cry watching series but this had me at times not going to lie.

Recomend to everybody. Especially if you like something unpredictable and original. Netflix did a whole lot of right in this series.
