[Spoilers]
I have some feedback. I didn't kiss Ned and told him we weren't a couple in the locker room, but at the party, when I tried to mess around with Vincent and Max, I lost relationship points with him with the dialogue saying they felt guilty for trying to cheat on him. Also, after letting Nathan have his way with me in the gym at night after the wrestling matches, the dialogue back in the dormitory is wondering what Ned would say about the interaction with him and how it would probably be best to not tell him about it. I found this odd because I had been gunning after Ron in my playthrough.
Also, I left the Headmaster's house before seeing Julian in the dog's outfit. However, when he returns with the dog collar on, one of the choices (Could be worse) is to bring up the dog's tail when there should have been no way to know about that.
