I`m actualy a guy but i love reading shoujo manga, and i think that Allen with Lenalee would be a cute couple but DGM is shounen, so this is impossible.
But not only "shounen" is problem for them ... > = )
That problem is Road Camelot !
Road is like Allen to and I think that together they are even cutier couple that Allen with Lenalee.
Road is noah but she is cuuute and cool ^_^
But for some reason i have feeling that Road would be killed = ( ...
