Amongst all the booze in page 4, there's a bottle of "Casillero del Diablo", a wine from Chile, yay! :D (Chilean wines are amongst the best in the world)
The mangaka has some Rin/Kyousuke LB doujins, (Uta and Ritsu seem to be modeled after them) so I doubt about the the chance of a NBR route.
This leaves only a heavy-drama outline for the future, I'm afraid.
