This is good. Like really good. I really like Yunifer so far, she's quite sensible I would say.
My guess is that Rael's awful boyfriend who keeps giving her stress is going to be the upcoming conflict. Maybe Yunifer will be convinced to help Rael break off her abusive relationship? Like, he would definitely go yandere and do some damage or something.
I have no idea how this will unfold. I'm excited.
