i imagine he's not my type, but with how much i enjoyed the previous routes (and that one cg i saw where he looks totally subby) i have been looking forward to this for a while!
Sad to say that Caine isn't submissive! After Gray (the most dominant guy), he comes in 2nd place in being dominant. Not submissive at all. Sorry :( He can be emotional throughout the route though.
You'll have to wait for Aiden, who is very submissive!
