What's there to notice??
Or maybe it's the fact that he got bit on his left arm, but the bite marks were on his right wrist on this page http://www.mangago.me/read-manga/afuresou_na_pool/mf/v01/c001/35/
Could be, could be... we may never know what the OP meant unless they come back to tell us. LOL However, it's kinda fun to pick a few frames apart once in a while. It helps me, who can't draw a staight line with a ruler, get more of a feel for what the mangaka went through to get each scene and frame just right - and what was overlooked by the editing department. (⌒▽⌒)
I have a friend who is an aspiring mangaka and the long hours he spends focused on one page makes even my eyes cross. I can imagine it isn't easy to pick out small errors without the help of a second pair of fresh eyes. I can't give enough credit to all the mangaka, assistants, editors and staff who put so much time and effort into making the works we all love so much.
Love it. But am I the only one who noticed this ---> http://www.mangago.me/read-manga/afuresou_na_pool/mf/v01/c001/33/
What is up with that? ROFL
