Okay so have seen both the original and the adaptation and I will say it without any regrets: The Original Is A 100x Better!

Now Comparison Time:
The love Gu Hai showed in these 15 episodes was way better than Wu Bai
The original series was about them unlike the adaptation where they cared about every character's story unfortunately and put equal focus on them
Of course the original had some faults but which show doesn't?
This drama is up on my high-priority list!
I was going to wish for a season 2 from the original but that is never going to happen so I will patiently wait for a season 2 from the adaptation
The adaptation itself was not bad but it was a bromance that you had to imagine as a BL.
However, I do understand the Chinese censorship.
The original was a straight-up BL and you don't need to imagine anything at all.
Both of them have a high rating from my side. I like both the couples and I think their chemistry is off the charts if compared with some leading Thai BLs.

Summary: Feel free to watch both stories and while you wait for another season, feel free to read more than 100 chapters of the book :D
