Anon you're a veteran because I've been making games for only 3 years now, if you've liked them since the first games then you deserve a medal.

Now I'll answer the rest of the ask under a spoiler cut because it kinda spoil a bit of Leila's character and also answer the question I got asked "what is Leila's worst trait"

Hellow hellow dreamy anon !

Aissata is in awe, you have such a beautiful style and confidence it impress her.

Rowan is a complicated actual answer. Shes does assume everyone should dress accordingly fancy and think you sense of style is really nice, but she struggle understanding why you don't adapt your outfit for occasions. It doesn't seems

Leila would think you look nice but would maybe be less interested in wanting to know more about you. It's bad to judge but Leila has always been gravitating toward simpler things and people, so someone really fancy would not be their to go type of person.

Aurore would feel kinda underdressed and would compare herself until she eventually get over it and simply appreciate your good taste. She would have a blast drawing you with all you pretty outfits.

Clem is kinda similar to Aurore in the sense that he'll feel underdressed and maybe childish compared to you. If you have a crush on them, I'm sorry to say but it will be way harder to get into a relationship because he'll always assume you deserve someone as fancy as you. Older clem would have less of that problem with that and serve a hype guy.

Alioth would probably treat you like royalty. He knows your wardrobe by heart, know what accessories match well with what and does try to match your fanciness when the two of you go out. He indule a lot in seeing yourself dolling up, it's quite sweet and he's very much in love. (Think how ponyo's dad looks at ponyo's mom)

Alioth : Just get out of it.

Rowan and Leila : Panic and probably go crazy really fast trying to make sense of what's happening. You're both dying

Aissata : she was there last tuesday during her work hour, she more worried about you learning about the existence of this place.

Clem : They're the one who brought Aissata there, he has work to do and now you being there means he'll have even more paper to do...

Aurore : With the superpower of dilusion and an insane amount of internet knoweldge, she would somehow find her way back. She's traumatized for life but she managed to get you two safe and sound.
