When I am saying this will keep you at the edge of your seat till the very end, I literally mean it.

This show is a complete package show.
From Acting,
Cinematography,
Casting,
Storytelling,
Story writing,
OSTs,
Direction everything is in sync and perfect.

Storyline :- Talking about the storyline it is very unique and extra ordinary. This drama is very convincing in a way that you may imagine that a parallel universe can actually exist.

One thing I like about this show is this one maintains balance between romance, mystery and suspense unlike other shows which mainly focuses on only romance.

Its a MUST WATCH show. Hands down.

PS :- If you are a fan of time travel you must not miss this masterpiece.
