So first I think it was brave for all the actors and the whole production team to make a BL drama in China especially with all the restrictions.
The acting in the drama was overall quite good as was the music.
However, the issues I had which made it quite difficult for me to finish it was the relationship between the two mains. Most of their skinship (touching) was forced. Gu Hai repeated forced himself onto Bai Luo Yin claiming it was normal and ok because they were 'bros'. I get that Bai Luo Yin didn't like properly shove him away at any point but you could tell it was a bit uncomfortable. I know lots of BL (Y) series also have issues with consent but in other ones I've seen, the issue has been handled better then it was here.
Also, the fact that they are step-brothers makes it murky water for a lot of people, however, as they do not find out about this until quite late in the drama, you can't blame the characters for this.
