great q! from what we’ve established so far, here are some of my hcs for her:

-she has a type A personality (controlling perfectionist). she’s the type to organize her closet by season, color, and occasion. super particular abt how she dresses bc it reflects how grounded and stable she feels. she needs control, and losing it would basically mean the destruction of the identity that’s been built for her in the laforteza household. she hates anything out of place and can’t stand mess whether it’s a physical space or someone’s behavior (a clean freak!) also very frigid, very uptight. knows how to carry herself. a rule-follower, but selectively (like how she’ll drink without needing any push)
-grew up in privileged environment, is tone-deaf and tends to look down on poor ppl who are less well-off
-unconsciously enjoys stressful situations, which explains that secret third thing she has going on with manon and the muse. she also has a tendency to indulge in risky situations, especially when she’s being told what to do
-secretly wants to be dominated (very much a “yes ma’am” type w the right person). she deals with decision fatigue from always being in control, so there’s a part of her that just wants to let go. also has a v bratty side when she feels like it
-even if she’s more submissive in private, her obsession w control still shows when it comes to someone she actually cares abt (like trying to fix manon, giving unsolicited advice, buying things for her). also will pay the bill when u go out for a date w/out being prompted
-gets scarily intense when she’s jealous (we haven’t seen it yet, but it’s coming LMAOOO stay tuned)
-very masochistic (and no i’m not elaborating u'll have to see it for urselves)
-identifies as straight, but that definitely gets shaken after her thing with manon / the muse.
-tends to see people as disposable (she’s always been self-focused until manon came along) as a result, she hasn’t really loved any of her past relationships or flings (she’s never actually felt that intoxicating kind of love yet)
-only really gets touchy (in a soft, non-sexual way) when she’s tipsy
-likes being overstimulated (ykwim)
-would probably be into ropeplay and semi-public situations. obv has praise kink! and loves being degraded
-a whitewashed asian who isn’t super in touch with her roots. she knows the language, but prefers not to speak it
-religious by family ties, not a devoted catholic
-fearful-avoidant (ooooh)
-would come w/out any touching (she's freaky like that)

ok so for imi!manon, it's pretty much a contrast w sophia's

-while sophia has a type a, i'd say imi!manon's kind of a mix of type a and b(?) bc manon lives in unapologetic filth,, though she knows exactly where everything is. she also smokes n she doesn't care if it'd stick to her clothing,,, she paints rather aggressively, staining her clothes in the process (she wouldn't care abt the stain). she would also prob style her own clothes. n unlike sophia, her sleeping sched's p much non-existent
-manon's hyper-independent (being working-class, on a scholarship) n is v much aware of the wealth gap. she also despises the elite n sees right through their fake societal rules. she loathes charity and pities anyone who thinks money alone solves problems (though she's aware money can solve it at the end of the day)
-if sophia enjoys stress, manon is the stressor to test ppl (sophia for example). tho she creates chaos herself, she still keeps her intention hidden, n often uses sarcasm as a defense mechanism to keep ppl from looking too closely at her actual emotions
-manon also craves control because that's the only thing she truly owns,,, a natural dominant i'd say (omg my total service top) but not just for the sexual thrill
-would argue w sophia if the latter pays for dinner w/out asking her (she'll lose her shit n start a fight over it). as explicitly showed in the fic, manon clearly would reject any financial help completely
-would totally fix sophia's leaky sink or cook for her,, or perhaps also physically intimidate someone who is bothering her w/out ever mentioning it
-p much territorial when jealous (she won't play mind games but instead will physically invade sophia's space and stare the other person down w murder in her eyes or leave hickeys for everyone to see just to prove a point
-in contrast w sophia, manon's p much sadistic (would push sophia to her absolute physical limits n she'd love every moment of it) but if there comes a time that she actually falls for the girl, she'd def have that tender streak for aftercare (tho she'd refuse to verbally acknowledge it)
-unapologetically queer!!! <3
-if sophia sees people as disposable, manon on the other hand, assumes that she's the disposable one, a play thing ppl get bored with once they get what they wanted from her
-terrified of genuine tenderness (if sophia ever initiates a soft gesture, manon will def pull away n flinch so hard)
-is p much the dominant in the relationship,,, (loves the control of tying someone up, inflicting pain, etc)
-dismissive-avoidant (oof)
