Aah, I could totally see that happening, makes sense!
I find that the easiest way to generally tell manga/manhwa/manhua apart is by the character names (ie: Miyano = Japanese = manga; Sangwoo = Korean = manwha; Zhan Zhengxi = Chinese = manhua). All these three languages are pretty distinct, so for the most part, the sounds of the names are too and it's generally straightforward to tell what country the name comes from.
Things can get dicey when a story uses westernized names though, lol ( ̄∇ ̄"). THEN I google it to check ;p
