First of all if you like shows with airtight plots then this isn't really for you. This is a fun show and the acting is great but there are plot and continuity holes you could sail the Titanic through! that being said I did greatly enjoy it.
The plot is not overly complex and the characters are not bogged down with angst and overly complicated choices that could save or end the world. Those kinds of shows have their place but this one just goes for the enjoyment of watching a show. I have only ever seen the ML in 'Well intentioned love' before and thought he had good comic timing which was shown as well in this show, his facial expressions and tone of voice where great. The only thing I would say is sometimes his body language was a little stilted, although that might be the character. The FL I have never seen before and her depiction of a woman with cat tendencies had me laughing alot.
The music. Well I must say I have watched alot of Chinese dramas with OST's that have stuck with me more than this one. It doesn't seem to jump out at you when you hear it or stick in your mind. It's good enough music but nothing special in my mind. Certainly not up there with some of the fantastic ones.
This show is a simple, fun show that you can stop and start, pick up easily after not watching it for a few days and turn off with a smile on your face. It's a bit of good fun and that's why I enjoyed it so much and would say to others to give it a try.
