well, the thing is, from what admittedly little i know on the subject (and also to my before-coffee head) that can be enough for them to want to start a relationship, but if they continue it for a bit it should really develop better reasons than that
also, if you’d prefer a better in-universe explanation, i wouldn’t be surprised if a few of them were misattribution of affection.
i actually read a book that had an okay romance aspect to it. it wasnt the main plot, but it was closely tied to it and it had a good buildup so yeah was good.
that wasnt why i was reading it, so it was unexpected, but the book was not unenjoyable
