Hey! If Adventure to the Beastkin tribe is on the plan, it would be interesting to have an option in the tribe, to get your own servant, for dominant players, or become servant yourself for the submissive players, based on the choices and events in the tribe. And those characters which are related to dominant/submissive routes (servants, masters, mistresses, etc.) can be added as guests in the temple, same as secondary characters like Hope and Rock.
Also, by reading scrolls at the temple, it is written that Beastkin take harem members, so something like that would be fun as well.
