The drama series goes in-depth with all the characters in Gu Man's novel. I have really enjoyed watching the tv series. In the drama series Wei Wei is portrayed as very feminine, and sweet not like in the movie version wherein Wei Wei is more tomboyish. There are also a lot of kissing scenes in the drama version. I ask myself is that necessary in order to spike the viewership ratings? There are also differences between the story line in the drama and movie. KO was a computer gamer who owns a shop, and not a chef. There's also differences between the character of Cao Guang.
If you want to know more about the characters in Gu Man's novel, I suggest you watch the series. All in all it has 30 episodes. I think Xiao Nai was played very well by Yang Yang and he is really very handsome. Jing Boran who played Xiao Nai in the movie is okay too, but I think Xiao Nai was played very well by Yang Yang. He also sang the OST of the drama. The characters complement each other very well. Xiao Nai the mysterious, silent type of guy who protects the sweet, smart, frail Wei Wei. The character of Xiao Nai is the ideal man of every girl, a loving and a very protective man over his girl. My favorite scenes are when he took care of Wei Wei when she got sick, and when he fetch her from the get-together party of online RPG players. Both the tv series and the movie is worth-watching. They're both my favorites!
