Both Q and Izumo are distrustful of others, fast on the uptake by erring on the side of cynical/assuming the worst of others, smart and impossibly smug about it. But Q is more comfortable relying on others than her canon counterpart, and thus leans heavily on B to run lives, make decisions on games and for emotional support. Despite the setting, there is less sense of urgency, so while she wants to step up and pull her weight by playing social games aggressively or hosting Lives, she just goes around demanding prezzies and headpets from her older siblings and trying to sort out her teenage feelings drama. Work is hard and people are hot, okay. She's got a crush on Camellia, who by merit of being in imeeji longer, is now the person of knowledge and authority in their relationship, which flips the dynamic of their canon relationship. She defers to Camellia's experience, and tries to make up for bullying her in the past by being nice (ish) and supportive.
With Pink, there are a A Lot of Complicated feelings. She has bad taste in guys and rage is apparently one hell of an aphrodisiac I guess. Q is more into him than Izumo was with Shima, because games have facilitated quite a bit of physical contact. So while she knows he's bad for backstabbing her and constantly teasing her, it's satisfying to rail on him without caring about his feelings. If she bullies someone she believes truly deserves it, then clearly it's okay.
