Although it's very sad to see how Eulalie`s friends refuse to support her dream, technically she doesn't support their life choices either. If they were such close friends Eula couldn't help but know they had their own careers, families and goals but she obviously thought that all this was frivolous idle nonsense that they would give up as soon as they took the first step towards meeting their ACTUAL dreams. It seems this is exactly how Eulalie`s friends and father treated her own hobbies!
I see a miscommunication here, in which both sides underestimated how serious they were in their words. Eulalie's friends were probably delighted to share with her what was happening in their lives while she was barely listening. However if Eula had dreamed of a paranormal agency for so long she couldn't help but discuss it with her friends all these years. And since she was sure they would like the new office, they never said a clear "no" to her, never indicated they had not been interested in it for a long time. I can easily imagine how they perceived Eula's dreams as meaningless, absent-minded chatter that she would never fulfill. Something so obviously preposterous that there's no point in talking about it out loud.
None of them listened to each other. And it probably went on for years until they found themselves _here_ realizing how much their life priorities had diverged.
It is much easier for us to empathize with Eulalie because firstly we have known her for a long time and these girls are just NPCs, and secondly Eulalie's vulnerability in this situation is highlighted by her socially disapproved interests: while her friends have the support of their families and partners, Eula has to lie to her own father. She is incredibly alone in this matter. But from the perspective of her friends they have jobs, families, one of them is expecting a baby, and then their friend says, "Yeah but how about leaving all this boring stuff behind and helping me open this dubious business? Wouldn't that be great?" No it wouldn't.
Oh what a wicked irony - unintentionally mistreating people the same way they mistreat you because that's the only way you've been taught.
Although I'm still angry that continues in Nevermore. "Eulalie believes in fairies lol," and you're turning into a huge anthropomorphic bat. What makes you think fairies don't exist.
