I don't get why in the hell a manga adaptation of an existing show could be so unfaithful to a point that could enrages fans of the show.
The author of the manga clearly favors Rin Setsu A (or Lin Xue Ya if you prefer the Chinese pronunciation) and changed a lot of the minor details to no only add some more screen time for him, but make him look way better than he was in the actual show, in which he was just a few steps away from being a horrible person.
Lots of moments that was meant to let other characters shine in the
show got changed in favor of Rin Setsu A. Even the supposed protagonist Sho Fu Kan of the source material can't escape this fate.
One could argue that I shouldn't compare the two, but see them as two separate things. The problem is that this manga isn't its own thing. Just like an anime adaptation of a manga or light novel, it owns a lot to its source material, and creative library should only be made with understanding and respect to the original. Which this manga clearly didn't have at least one of those in mind.
Basically, skip this and go watch the puppet show.
