I've grown to like Himawari after her revelation, and it's a pity she didn't get to be there. Perhaps the scene was already too crowded, and they just sticked with the final love interest or something.

I'd say that Ken/Take are only similar in the bento/snark part, although the role are inverted (aka, the one making the bento is willing to do so, and the other one doesn't want it and complains about it). I like them better than D/W because they make me laugh louder, but it's one of those little things I disagree with the whole fandom.
