... well, see. There are some mysteriously appearing espers, who have arrived without any kind of notice to sign on, with very quickly drafted contracts, and also, unrelatedly, the Korean classes are getting some new students. Funny, that. Of course, this is not particularly obvious information to most people in Quasar, but Minseo is very easily bored, and sensory deprivation is very easily boring, and she's a little snoop. Life isn't fair, and sensor privilege is real. She can learn anything she wants if she knows where to look, and when it comes to Quasar, she does. Sucks to suck.
(Plus, she's seen this dance before, with Da-eun. Things have since settled down such that she might even be able to visit her family in Vietnam again someday, but, well. This is not the first time Quasar poached an esper in a bad situation.)
So, anyway, Si-yeon gets a message that goes like:
I hear there are some new people looking to test out compatibilities at Quasar? either of them comfy with co-sleeping? I'd like to let Da-eun go actually read to her kids
It is very telling, that she quietly sent this message to Si-yeon personally, over a comm channel that doesn't log history. What? She's not an amateur.
(Relatedly, she's gotten people convinced that the random foreign talking in the lobby was German by anyone that's gossiping, by going 'Oh, yeah, I saw, it was definitely German,' with her bullshit sensor privilege. You're welcome.)
