I love the dynamics between the student and the teacher. That alone would have been enough to maintain my interest, the probable abuse-storyline is a bit overboard in this. But oh well, let's see where it goes. I really dig the dynamics.
It's a whole lot of complex feelings. Sensei is trying to understand what's happening, also she has no confidence at all. None has ever liked her back? I imagine she didn't even tell them, because I can't imagine she would be rejected all the time as she is pretty decent (well, life sucks sometimes, you never know).
Then the student, she is forcefull and obviously has a fucked up life (none of your parents want you, wtf? best parents ever). We don't know her motifs, so we are on the same page as sensei.
I also got really bad vibes from the tutor. Maybe student wants to reproduce what is happening to her while being the one in charge. But that would just be too fucked up, please no. But many things actually point in this direction.
Anyway, as it is I hope she ends up living with sensei in the end <3
