I've read a lot of people complaining about this series but I personally really liked it.
Yes, it's slow paced and I think the broadcasting team made a bad decision by releasing one episode a week. When I saw that, I decided to wait until the end of the series so that I can watch it in one go and that was a pretty good decision that I've made because I'm satisfied with the result.
I think it is a pretty realistic story, the characters not able to be upfront with their feelings because they're scared. It happens to a lot of people (and I'm one of it). So maybe for a show, it is annoying but I liked it a lot.
The only thing that I wasn't quite happy with was the end and the trio Shi Lei, Zi Tong and Zhao Gang. To me, it wasn't necessary as Shi Lei was already ready to confess his feelings.
Also, I was suprised to see Wayne! Is his goal to make a cameo in every BL show from Taiwan (and Japan)?
