It's not just any show that can keep me interested for the entirety of it, this show did! The plot is original and creative and as a gaming lover I loved the whole concept of the vr game and how they made it look like a game was really being played.

All the actors did a great job especially Hyunbin who carried the show on his shoulders, I already had a crush on him since secret garden and now I admire him even more.

The romance was good, they had good chemistry, and there was just the right amount of it, it wasn't the main focus of the show.

If I'm not mistaken there was only one ost that played during romance scenes and I wished there were more although I did like that one song.

Of course there are aspects that could have been better explained or more detailed like Park Shin Hye's character, or Chanyeol's character, etc, but the show evolved around Jin woo mainly so I understand. The ending could have also been less open ended and more clear but it was good and I personally liked it.
