A refreshing piece of work in this entertainment (drama) industry.
Firstly, the cast. Thumbs up to the director who had cast Zheng Shuang and Yang Yang for this drama. I knew Zheng Shuang from this drama, and although some people say she may not be the right person for this role as she's too skiny, I think she's the perfect fit. In terms of portraying her character, I think she did a marvelous job. Yang Yang did well in acting Xiao Nai, the high and mighty male lead with a cool personality. It was extremely cute to see Zheng Shuang conversing with Yang Yang, especially when Zheng Shuang acts shy in the drama.
Secondly, the plot. The game part of the show was the only reason why I decided to give this show a go, since I do not know anything about the cast then. I find the game element was well incorporated into the show, as it developed the story well (bring the male and female lead together).
Thirdly, the music. The opening was memorable. It really fit the school-themed drama and the romance between two youths (the leads).
On a final note, I will like to add that it is definitely worth rewatching as I have re-watched twice already.
Even if you have read the chinese manhua or have watched the movie already, you should definitely give this a try!
