I thought I followed the walk through by the letter but somehow I must be doing something wrong myself as I'm not getting any corruption content myself.
I have also followed people advise on here about the sex scenes as they said that is where you get the main corruption points, but still nothing!!
So I'm thinking, am I'm doing something wrong, or is the game looking at my old saves and preventing me from getting the corruption scenes, it's just a thought as I have now run out of ideas.
I tried maybe 15 playthrough; not kidding; to finally reach the corruption path. you dont have to hate her. just corrupt her without getting exclusive. I cant tell any further than this coz I dont know which choices actually worked for me.
