Could you make it so that Yuna can switch places with Kaede if she wakes up, so Yuna will be in the sleeping bag and Kaede will be on the bed. This will give the opportunity to make new animations with Yuna in a sleeping bed and the player also can fuck with Kaede in the same way as with Yuna
Of course you think it's a good idea, as does everyone think of their ideas :D
Unfortunately I don't think it'll happen though, keep in mind that Yuna is the FMC of the game, other characters are just sidekicks, besides dev plans to add some scenes and stuff to other females in the game as well, so either kaede will have to wait more for her turn again or she won't get anything more at all
