Apart from the fact that they have animal traits, I don't quite see a lot of similarities. This manhua has a unique style that you can't find everywhere, the author manages to surprise you with funny and smart details that you can observe in the corners of the pages, like chibi characters and animals or funny character faces (a lot more that you expect from a yaoi manhua, usually authors create beautiful protagonists and they don't risk making them look ugly not for a second, but this author does it and they don't seem ugly to me); They also know how to pass smoothly from a funny scene to a sexy one.
Instead, sex pistols definitely has a japanise style, it is more dramatic and it gets gloomy sometimes.
I don't know why, but I always thingking that this sory similiar to sex pistols.
