I love a good pining-for-my-best-friend story, and this fit the bill. The two main characters definitely have chemistry, and I loved the way Gong hid his feelings for a long time before finally confessing. I know a bit of angst is almost always present, so I wasn't surprised when it happened. What I have issue with is the manner in which it happened because, although it could have made sense, the way it was written it didn't really. Gong had his reasons, but I feel we should have seen him go through them rather than be left guessing as Shou was. Still, the incredibly romantic finale made up for it.
The secondary couple was a wonderful surprise. These two also had great chemistry, and I found myself rooting for them. The addition of Ze's daughter made them even sweeter. All in all, this series (for the most part) dripped in sweetness and had many humorous scenes as well.
