Alright after having watched several of Nerissa's collabs, ive come to the conclusion she just needs to collab with the girls who don't play hard into yuri. She's relatively fine and gets along with Bijou or FuwaMoco when its just themselves, though she does still occasionally make some horny/perverted remark, she doesn't really try to flirt with them. Whereas with the likes of Ollie and Kiara, one has no concept in moderation or being calm while the other is a bit desperate in having people like her so its understandable that she really feeds into it. Whilst Shiori isn't really all that much of a flirt, she's actively encouraging that behavior and most of the time is actually the one initiating it by talking about Nerissa's sexuality or perverseness before she even tries to flirt. It's just unfortunate that Nerissa's first collabs outside of Advent have to be the ones who like to go hard in forming ships if they can.
