On a scale of 1-10 how possessive/jealous are the RO's?
Prue/Rue – they aren’t possessive at all. At this stage of the story, if they sensed a real emotional threat to their relationship with MC, they wouldn’t say anything; they'd just suffer in silence, channeling their misery into music. But they’re only 22, early in their career, before their first tour, and they haven't hit any real bumps in the road in their relationship with MC yet.
Mark - he’s like a 0 when he’s detached, but he can jump straight to a 10, simply because he’s capable of eliminating a source of jealousy without a shred of remorse. But, it’s not very likely he’d ever reach that level, as he generally perceives himself as superior to everyone else.
Sieun can be overprotective and intensely attached. Part of it comes from their fear of betrayal, and during intimacy, they become very intense and a little possessive, simply because they care so deeply. At the same time, since a large part of their life is dedicated to saving others, they highly value their own space and respect their partner's independence.
Seb can’t imagine life without MC, yet he has no desire to control them. It's completely against his nature.
