There is always a room for improvement.
For this drama, I don't think I would put it in my recommended list, however I could introduce it for those who are looking for something to watch in a mean time.
I have no problem with the actors and actresses they chose, and to be honest Cai XuKun did give emotions and he properly did his part as the lead of the drama.
The music is perfect also, I have respects to the artists who composed the OST's but the story is just a bit disappointing. I'm not saying that it's bad. It's just something is a miss.
Also the ending is just so unsatisfying. The story is not resolved and somehow left the viewers hanging and just empty.
One good things is that its very very light, the conflicts aren't that serious and easily fixed. The lead is quirky, and just out of XuKun's original personality which added a comedic flavor in the drama.
Overall the drama ain't that bad, but still a bit disappointing.
