I liked the show. The cast are good they all worked for it. It may be a bit like while you are sleeping but I really enjoyed this better. The viral video on 2 boys fanboying twice made me watch this and I was thankful i did.

I love the humor of the series the actors/actress really are impressive. The the twist really good and is really enjoyable, although I really missed Bo Na at the last episodes I really kind of wish he can go back again just to see their bonding moments. I salute Dong Taek he's the real MVP. This is the first kdrama series that I really looked foward to and even waited every week.

If what happens in the other world must happen in his world. Then what happen in his world must also happen in the other world. With all the I was trying to point out that it was safe to say the they were saved in his world by Dong Taek and the other parallel world where Bo Na already exist, Dong Taek should also done the same thing and saved them.

With all that said it is a perfect 10 for me.
