I find it funny that most of you here think Stan is a creep and for jerking off to her photos and invaded Lena's privacy during sex, but you know what it's YOU who enable that. You can be nice to him as Lena as much as you want but there has to be some boundaries.
If you ask for money to let him take pictures then I'm pretty sure we can forgive an shy, introvert, overweight guy, who mostly keep to himself in a room, for jerking off to the photo of beautiful flatmate who is kind enough to walk around in her panties (Also, those photos are kinda service rendered since he paid her to be a model.) If you are mad at him he explains that he thought it's okay since Lena has stalkfap account, even Lena thought it was understandable. And if you still protect him after that he will then know no boundaries because he think it's okay to YOU. (Also, if you reprimand him, he would not peek.)
But if Lena just says she can help him out with camera, but not taking her shirt off. Then you wouldn't find him jerking off to them (that we know) and he would not come in during sex scene as all.
I can't fully agree on this one. While yes, the player enables those situations, this kind of argument is true after the fact. In the moment of making the decision, nor Lena, nor the player, don't know what kind of consequences their action is going to bring. It's a bit similar to victim-blaming I'd say. Could the situation be avoided if Lena didn't pose nude for Stan? Yes, absolutely. But Lena is not a seer who can accurately predict the future. She can choose to trust Stan to TRY to be professional (since he stated it to be his goal) and show kindness because she sees that Louise treats him unfairly and feels a bit of pity for him. Lena, nor the player, can't be blamed for that. Before this update, many players believed him to be a nice guy and felt pity for him because of the way Louise bullied him. The consequence, while predictable to some, turned out to be completely unexpected to others. And even when Lena is faced with the choice to get mad at him or not, it's not 100% clear that Stan will act like the creep that he turned out to be.
After all, the girls barged in on him, disregarding his privacy. It would be the same as if Stan barged into Lena's room, catching her nude with a dildo in her hand while looking at Jeremy's pics on Louise's phone. Lena can feel slightly disgusted at Stan, but once again, she can realize that they shouldn't have entered his room without giving him time to answer first and not show her anger simply because she's a nice person and shows her empathy. She chooses to be kind to him and expects the same in return. Instead of being thankful and glad that the situation ended without the shitstorm, he chooses to act like a creep and peeps on Lena at any given moment. THAT is where things go from awkward to completely unacceptable (for Lena who values her privacy). And the player can't be accountable for this consequence, because, like Lena, they can be a bit naive.
But in the end, I think it just proves how well Eva wrote this scene that you don't really know what to prioritize. Do you choose to scold Stan for breaking Lena's trust and set up strict boundaries or do you prioritize your friendship with Stan and choose to act selflessly if a bit naive? Do you try to believe in people or do you become more like Louise/Ivy and expect all guys to be creeps by default?
