Nice game, still quite a way to go.
That said, the slavery part is not in the game yet, at best it is possible to mod npc as to have the PC indicated as Master (over their relationship lines) but since there is no (?) status on the PC relationship ? The game quite lack a wiki/resource document as to know what.
Since the developer also added a second "know traits" I guess an "discovery" mechanism is around. Enforcing this, the board is asking for a "cumslut", a trait currently not know to anyone in my school/over the listed npc..
Quite more to be added, no surprise is there ?
