Cecillia is (or was) the only one with "nice" content, you could make her accept you as a lover (telling her about her boyfriend cheating on her when you have positive affection), you could have consensual sex with her during "party" night while her boyfriend was passed out.... I don't know about her photoshoot options I'm not sure that was available the last time I tried "nice"Correct me if I'm wrong guys but, after playing a bit, I'm getting the feeling that with Cecilia it's more rewarding the good path (vanilla photoshoot or no shoot at all) than the evil one (nude photos with Dominic there). I haven't progressed that much though, so I 'd like to hear from you and see what you think about it. I haven't been able to solve the Emma's mystery too(whether you can move up things with her before Doug explains his plan to trap her, cause URM seems to suggest you can get her to flash the boobs and share the pic with Doug later in the evening, when he calls to explain his plan...). I really hope the kind Dev can help me with that...
I suspect you won't be able to do anything with Emma before Doug proposes his plan, like I said before my money is on it being an option if you turn him down and maybe warn her?
