Well, yeah he does. It's also আরো of the fact of Natsuki Takaya's style changing আপনি know? Yuki began looking আরো masculine, the art improved incredibly, which is inevitable. But I do agree that Kyo looks আরো like Katsuya ^^;
He does, but I'm pretty sure it was on purpose. I think I read somewhere that the লেখক wanted to প্রদর্শনী the characters growing up both emotionally and physically, so Yuki, Kyo, (the boys in particular) got আরো filled out along the way. That would be challenging wouldn't it? Not only making sure each drawing remained true to the character, but tweaking them across several volumes to be a little taller/more filled out.
I think that Natsuki Takaya was trying to make all of the characters look older, since they are ageing within the manga. It started out when they were starting High School, and then it ends when they finish High School. And Nastuki's drawing style has changed as well.
