Shounen -> Weirdly homoerotic and shoujo-y -> Is the publisher SQEX? -> ...Yup.
I do love that part of Square-Enix.
But which also means, for those asking, the chances of it having anything other than the light homoerotic teasing seen so far are quite low—they have published actual shounen-ai periodically, but very rarely, and possibly have never done so in this particular publication, GFantasy. And I'd be very surprised to see it happen here in this particular case. Though there is the possibility of ultimately having "highly ambiguous statements open to interpretation" and things of that nature, I suppose.
