There are specific strings on stuff. Like if you choose only girlfriend stuff and don't sleep with anyone else, you miss out on like 60% or so of the game. Even the NTR is different, to activate it on the bar path lily needs to have more Queen than anything else but, on the college path she needs slave over 4 and to be higher than queen or girlfriend. Chapter 1 has a GF end, Queen end, slave end, then a mean slave end?, Queen ntr end, Slave ntr end and a bad end. All these have scenes, and if you choose the ntr scenes you miss out on the scenes with Lilly. Each path between Bar and College has multiple scenes you only get on their paths.
Chapter 2 has several scenes based on your favor with the mom or sister, basically need to focus one or the other UNLESS you have gone the slave route with Lilly then you can use equal numbers numbers of favor with them both while reaching the needed thresholds, I think its 3 and 3 then 4 and 4 or something the guide tells you, then you can get both of them and Lilly. This gives some scenes in Chapter 3. Its kind of a clunky way of doing things.
