No, I think you're spot on. The name of the manga is "Overtake" so the differences caused by the age gap, and the competitive spirit and Kabuki elements with which Kengo approaches those differences, writ large in the first story, whereas the second one deals with failure of communication about intent. Age-related differences are the central theme of the manga, and just because it is a manga doesn't mean it can't deal with subtle themes.
i don't know how Fumiya is able to be in a relationship with kengo. i mean kengo is a child, so he acts on impulse. But Fumiya is amazing, he has so much patients to stay in this type of relationship. So i feel that they should have waited before they got into a relationship :/
I don't hate kengo or anything, its just.. he really is a child, not very mature yet, he's cute, but he's a child. I don't really see how Fumiya can stand to be in a serious relationship with kengo :S
haaah~ i'm probably looking at this too seriously, i need to remind myself that it is a manga after all >.<
