Mild spoilers ahead!
I have an irresistible urge to continue to whine about Octavia and I guess Claudia too, now.
Have been giving additional thought on why I wasn't completely satisfied with her scene at Day 18 and I guess I know the reason now. To put it short this scene could've happened between any of the club's girls - and any of the patrons.
It doesn't really takes into account her personality, nor does it show any changes in her personality convincingly. She's just all of a sudden transformed into a professional sex worker, who just diligently does her job in a nonchalant manner, almost as if it is everyday routine for her. As I just said, any Mask's girl could be on her place and the scene wouldn't change much. Perhaps that's what developers are aiming for; perhaps they want to show her transformation into a professional "escort" in the corruption path. If that's the case, they have every right to do that. The problem, however, is that we haven't been shown that transformation, it already happened somewhere off-stage. As if by a turn of some switch. In the first scene she was reluctant, ashamed yet determined. Now she's just determined to please her customer. And that's only the second scene we have with her! That's it I guess, her corruption path is over, time for MC to move on to other girls.
Or rather let's move on to MC. Same as with Octavia, the scene doesn't really show his personality or character development. He just sits and accepts anything she does. His only emotion is being (pleasantly) surprised. He doesn't corrupt her. He's being rather a passive object, not an active party. In this scene a player doesn't exercise any agency, and MC doesn't display any agency. Which is strange, since earlier in the game MC was thinking to himself "prepare your anus, Octavia, I'm gonna take my revenge on you, and my cock is as hard as this morning's exam". But when it came to the scene, all he's doing is just sitting and thinking to himself "wow, I can't believe what's happening". Instead of him saying "tonight I'm going to request something extra from you", we have her going "tonight I'm going to do something extra".
There's hardly any meaningful interaction between them, just physical sex. Sex between a prostitute ready to do that with anyone and her faceless customer. Not between Octavia and MC.
Things could've been different, more emotional, more personal, more intimate. There's a plethora of ways to develop their relationship deeper than occasional sex. I imagine someone like her would try to somehow rationalize the whole situation she's in, instead of just easily accepting that she's a prostitute now. For example she could start to appreciate the anonymous MC, start thinking about him not just as a walking prick but as of "the man who chose me over all the other girls". She's less experienced, she lacks "training", she's clumsy - and yet this rich, young, fit stud chose her. So she could rationalize what she does by going "I'm not just a sex toy for him, he chose me because I'm special in his eyes, may be because I'm very beautiful, may be there's something between us". Sort of the Stockholm syndrome. Or she could believe that pleasing MC protects her from something worse - if not for him, her exclusive visitor, she would probably end up "servicing" ugly fat guys every evening; a new guy every evening, doing god knows what to her. Or ironically enough she could perceive MC as her teacher that, with his requests, helps her to awaken and develop parts of her sexuality she didn't even know existed - while in reality he's just a horny teenager living out his fantasies.
On that note I will wrap up my rant. Of course, I don't expect the devs to change what's already in the game, I merely want to facilitate the discussion on character's personalities and motives.
