ah yes, getting the valanthe lore dump without roleplaying for it....................a pro strategy............................... (ily)
— is your oc a very good flirt? are they charming?
no and no. despite having quite an excellent charisma stat, valanthe is neither a.) good at flirting, nor b.) charming. at least, not initially. it takes her a long time to warm up to someone even in a platonic sense; once she does open up in a romantic way to someone, this also eases a little, but not by much. maybe some find her romantic ineptitude charming!
— what does your oc find irresistible in others?
smarts! she is painfully, cruelly bisexual, but i would almost argue it's nearing sapiosexual, how much she needs someone to be intelligent. mostly because there is nothing sexier to her than when someone goes "actually, you're wrong" to her and then has the information to back it up, but also because she might die if her partner isn't smarter than her.
(you think i'm kidding but her intelligence is literally at 8. please help her.)
— into public displays of affection or are they more reserved?
definitely leans into reserved. i like to think that even after multiple years of an established relationship, valanthe might publicly punch her paramour in the arm and go "good work, champ" after a particularly grueling fight instead of like, hugging them or kissing them. in private she's much more open.
— what’s a surefire way to make your oc get flustered?
give her flowers! or remember something she said and point it out to her later. or, genuinely, anything that you might consider a cheesy-romantic gesture ("i read this poem and thought of you" type of shit). she'll probably just grimace and scratch her forehead and awkwardly exit the conversation, but you can bet that girl is gonna be thinking about it for daaaaays.
