Right now, I'm in "Tsukushi deserves better than both of them in the romantic department" mode, though they do make great (if argumentative) friends.

I run into the same problem with Rui (or for that matter any of the F4) that I run into with Tsukasa and Tsukushi. What in the heck could an imagin do to fulfil his wish? :(

(Or at least try; I'm still figuring out how the Bat Imagin managed to completely keep looking for that keyholder when it looked like he had an image of it.)
