I fully understand your bitter feeling about it. I hope I can take that a little off of you. Since it is a popular fetish that many also look forward to see, I won't be able to avoid putting it in the game.
However, the way I always intended this game to be, is that nothing is canon as long as the player doesn't want it to be. Everything is up to the player. It is their game and their world. If Ray and Ruko shall be lovers, fine, so be it. If Ray and Ruko shall hate eachother and don't want nothing to do with the other, fine, so be it.
The player basically makes their own canon story out of this. Nothing in this game is canon, as long as you don't want it to be! If you rather have your desires all for yourself, they are all yours!
