I have lost count of many things I've added. Here are the main ones:
-You have neighbours! Mark has occupied a nearby home, enslaving the 2 women living inside. He's strong, already master of his house and might start looking in your general direction. He'll come to visit from time to time. His two slaves are interesting too.

-> Interactions with Mark in his guest room
->Interactions between Mark and his slaves in his master room
->interactions with mother, sister, female father and female MC when Mark comes to visit.
->Your mother could be enslaved if you get too much on his nerves.
->Speaking of getting on his nerves, messing with his slaves is dangerous, and you might have to sacrifice something to make it up to him. Only you and your mother can be sacrifices atm.

->Mark's cellphone is often left in the livingroom, you might write to something he'd fancy meeting to get on his good side.
->You can try to fight him in several scenes, even asking your father for help.
-Kitchen scenes with female Mc
-Father may now wake you up if mc is female
-Surely some other things I've forgotten about. Go explore!
