Maybe it's that thing when she projects her insecurities onto the MC and feels that because she's so well-liked by the knights as well as because she had the 'audacity' to come and propose to the ML, she hates her because she is tainting the temple when she doesn't see that her own pettiness is making her look infinitely worse
Right!? She projects her insecurities to the mc to the point that she can't see it ugh! If she just did a bit of self reflection she will see what shes doing!! At this point of the story instead of a concerned and sassy priestess she could've become her entire role became a whiny little bitch. Such nice character wasted
Girl I understand the speculation and the wariness of the blue haired priestess but at this point she's just acting like a bitch
