If I am correct, this might be before Go Jun completed Word of Honor. His Censorship. portrayed the character well. The
entire cast, from lead to support did an excellent job. Production might be lacking a little in wardrobe; viewers can actually tell which scenes were filmed at the same day due to wardrobes. Props integration need a Lil work (mannequin in the well).
I feel it could have been directed better because the sequencing seems off a couple of times although it didn't really ruin the story.
Last but not least, I read that there was originally an uncut version of this series that made it more fulfilling to watch. Sadly, that may be buried since this was released 6 years ago. For a Chinese bromance series, don't expect what you normally see in a typical Korean, Japanese and Thai BL works. The closest this will get is a brotherhood relationship that hints that there could be more but then suddenly a scene or line is inserted that would tell pull you back that it's nothing more. There was a scene where the second leading man while in bed with Go Jun told Go Jun he isn't only being nice to him because of his sister and that will tell him in the future. the entire series ended without any scene revealing that reason.

I recommend this to any Go Jun followers because this shows his early talent that can be compared to his recent ones.
Kudos to the producer for bravely producing this series and doing their best to meet the strict censorship.
