Honestly speaking I have been thinking of watching this show for 2 years. And now I have completed this show.
In one sentance - Slow start that you wanna drop it but if you will wait, you'll get to experience an amazing show. So Dont Drop it.
ep 1 and 2 - present time ( slow and confusing )
ep 3 - 32 - Flashback ( You'll also understand the first two episodes better after watching these eps ).
ep 33 - 50 - present time ( & the real excitement is here ).
Although the Novel is Utterly fantastic ? but but but the show is not lagging behind in potraying main leads emotions in a non sexual ( due to censorship in China ) way.

My three most favourite things in this show :-
1. Eyes of Xiao Zhan
2. Smile of Xiao Zhan
3. The Gaze of Wang Yibo ( Chills on the body )

Definitely going in my REWATCH list.
JUST GO FOR IT.
