SS501 comeback concept inspiration from manga?

Thats what i think too when saw their picture for the first time... Personally i like it.. Its cool.. I really thought they like walking manga character.. for a jacket concept photoshoot i think its so cool and unique...

anyways this concept attract many korean netizens opinion.. and so far... the response is positive because its kinda unique...

this is some manga pics circulated in many korean cafes which alleged as their reference...
This concept reminds me alot about their concept in ST.01 Now, but it is darker ^^
